The Calculator app might be one in all Apple’s most-used apps on the iPhone, but I meet individuals all the time that do not know all the little tips there are to utilizing it extra effectively. Chances are you’ll know most of them, however there’s an opportunity you do not know each single one or just forgot about them.

What a “hidden trick” is to some individuals may be apparent to others, so be happy to skip proper by those you already know within the beneath checklist. This roundup is supposed for everybody, from a complete smartphone beginner to any individual who’s owned iPhones since iPhones have been a factor, and even skilled mathematicians. For probably the most half, I’ve sorted it by the simplest, most intuitive actions to the extra superior ones, so skip forward if that you must.

Tip 1: Open the Calculator

OK, so that is fairly apparent…or is it? Sure, you may faucet the Calculator app icon on the house display screen, however there are different methods to open Calculator. Listed here are simply among the methods you would do it:

  • Faucet its icon on the house display screen.
  • Faucet its icon within the App Library. (iOS 14 and later solely.)
  • Faucet its icon in Search.
  • Faucet its icon in Management Heart.
  • Say or sort “Calculator” to Siri or Hey Siri.
  • Double- or triple-tap the again of your iPhone. (iOS 14 and later solely — see Tip 16 beneath.)

Tip 2: Unlock the Scientific Calculator

You have almost certainly stumbled upon this accidentally, however I do know some individuals who’ve by no means turned their iPhone sideways besides to observe Netflix or Hulu. So rotate your iPhone into panorama orientation, and the calculator will change routinely from the usual calculator (for fundamental arithmetic calculations) to the scientific calculator (for exponential, logarithmic, and trigonometric features).

You may discover extra superior choices like cosine (cos), tangent (tan), sq. root (v), pure logarithm (ln), and the pseudo-random quantity generator (Rand) which can be most helpful for science, engineering, and superior arithmetic.

Tip 3: Erase Digits You Simply Entered

If you happen to meant to sort 523 as a substitute of 532, “Shake to Undo” will not take away your previous few digits since that function is disabled in Calculator. However there’s a neater technique to take away digits entered. Simply swipe both left or proper on the quantity discipline, or actually, anyplace above the keys, and the final digit might be deleted. If that you must eliminate two, swipe once more. Three? You get the image. If it is the entire quantity that you must redo, see the subsequent tip.

Tip 4: Erase Entire Numbers You Simply Entered

Everytime you sort a whole quantity in that is unsuitable, there is a tremendous fast technique to repair the error. Once more, “Shake to Undo” will not work because it’s disabled in Calculator. As an alternative, you may simply clear the show utilizing the “C” key, which stands for “Clear.” It will not erase all your progress — simply the final entry. So when you entered 1,242 x 324 however meant it to be 1,242 x 423, hit “C,” then enter 423 and proceed together with your calculation.

Tip 5: Begin All Over Once more

If you happen to do want to start out from scratch, you may wish to use the “AC” key, which stands for “All Clear.” If you happen to do not see an “AC” button, that is as a result of it solely seems after you’ve got cleared the show, so you may need to hit “C” first earlier than “AC” will seem as a substitute. Faucet that to start out yet again. (Be aware that force-quitting Calculator will not work since it is going to nonetheless bear in mind your final end result.)

Tip 6: Copy & Paste Numbers

Apple’s assist pages solely talked about one technique to copy and paste numbers in Calculator, however there are literally many alternative methods to go about it. If you happen to’re making an attempt to stick a quantity in, you may solely see a “Paste” choice if you have already got a quantity saved in your clipboard.

  • Faucet-and-hold the quantity presently displayed. Faucet “Copy” within the menu to repeat the quantity, or faucet “Paste” you probably have a quantity saved in your clipboard that you simply wish to use within the calculation.
  • Double-tap the quantity presently displayed. Faucet “Copy” within the menu to repeat the quantity, or faucet “Paste” you probably have a quantity saved in your clipboard that you simply wish to use within the calculation.
  • Faucet the show with three fingers. Faucet the Copy icon (center button) to repeat the quantity presently displayed, or faucet the Paste icon (to the precise of Copy) you probably have a quantity saved in your clipboard that you simply wish to use within the calculation. (iOS 13 and later solely.)
  • Pinch the show with three fingers. This can copy the presently displayed quantity.
  • Faucet the show with three fingers and unfold them. Consider it as the other of a three-finger pinch. This can paste the presently displayed quantity. (iOS 13 and later solely.)

Tip 7: Copy the Final End result

If you happen to’re nonetheless within the Calculator app and want to repeat the present end result, you’ll simply use one of many choices above. Nevertheless, when you’re now not within the Calculator app, there are nonetheless just a few methods to do it.

  • Swipe open the Management Heart, then long-press the Calculator icon.
  • Lengthy-press the Calculator app icon on the house display screen.
  • Lengthy-press the Calculator app icon within the App Library.
  • Lengthy-press the Calculator app icon in Search.

Both method, you may see an choice to “Copy Final End result,” and it’ll checklist the final end result, so you already know that it is the proper one. Your final end result ought to even present up after force-quitting Calculator.

Dwelling display screen (left), Management Heart (center), and Search (proper).

Tip 8: Carry out Calculations in Search

Now that we have talked about Search, it is good to know which you could carry out mathematical calculations proper from it as a substitute of opening the Calculator app in any respect. To open Search, swipe down on your house display screen or open the In the present day View both by swiping to the far left aspect of your house display screen or lock display screen.

Then, enter in your equation or components. A field straight beneath the Search discipline will seem together with your end result. Faucet that, and it will take you proper to Calculator with the end result already entered, in case you wish to proceed your math downside there.

You will not have the ability to carry out superior calculations because the keys restrict you in your keyboard, however that is solvable by putting in a keyboard with extra calculator features. Third-party keyboards you should utilize in Search embrace Numboard – Scientific Keyboard, Calcul Keyboard, Calculator KeyBoard, Calculator Keyboard – Sooner, and SciKey – Scientific Keyboard. Nevertheless, not all mathematical operators, symbols, variables, constants, and features are supported in Search, so you should still have to open Calculator when you see ones that do not work.

Tip 9: Make Siri Do the Work for You

Whether or not you employ Kind to Siri, Hey Siri, or the Siri shortcut, you may ask it to carry out your calculations for you, in some circumstances, with out lifting a finger. Simply say one thing like:

  • “What’s 74 instances 14?”
  • “What’s 28 % of 225?”
  • “What’s one-third of 456?”

If you happen to attempt to ask it extra superior issues, like algebraic expressions, Siri will not use Calculator to offer you outcomes. As an alternative, it will use one thing like WolframAlpha or Safari to get you solutions or hyperlinks to potential solutions. For instance, “What’s 15% of 45% of 1.4?” That pulls up WolframAlpha for me with the end result 0.0945.

Tip 10: Rethink How You Use the Buttons

When utilizing Calculator, most of you’ll enter a quantity, hit a logo, sort in some extra numbers, hit one other image, and so forth. However that is not the one technique to do it. As an instance you wish to convert % into decimal type. Usually, you’ll sort the quantity, then hit the % key. Nevertheless, you can even tap-and-hold the % key first, then sort the quantity and let go of the % key to get the identical end result. Attempt it with different buttons and symbols, and also you may simply discover that it is sooner in some circumstances.

Tip 11: Faucet ‘2nd’ to Discover Extra Choices

If you happen to’re new to scientific calculators, this may occasionally come in useful. Since all the choices will not match on the keyboard, you may faucet the “2nd” key to alter among the different keys. As an example, sin will flip into sin-1, ln into logY, eX to yX, and so forth.

Tip 12: Get a Random Quantity

Within the scientific calculator, there is a “RAND” key, which is a random generator perform that produces a quantity between zero (0) and one (1). Extra particularly, it is a pseudo-random quantity as a result of software program can’t randomly generate the end result of unpredictable pure phenomena like rolling cube or measuring atmospheric noise. With it, you may carry out a calculation similar to emulating rolling cube. This weblog put up can clarify it higher than I can.

Tip 13: Make Your iPhone Converse the Numbers

If you wish to know the way the quantity is spoken, you can also make your iPhone communicate it to you. Within the Calculator app, you may tap-and-hold the present quantity or double-tap it, then choose “Converse” from the menu to listen to it spoken as phrases, or “Spell” to have every digit and image spoken individually so as. If you happen to do not see these menu choices, allow it by way of the “Accessibility” preferences in Settings:

  • Spoken Content material –> Converse Choice (iOS 13 and later)
  • Speech –> Converse Choice (iOS 12 and older)

Tip 14: Change the Calculator’s Colour

There aren’t some ways to alter the Calculator’s colours, however that does not imply it is inconceivable. Darkish Mode in iOS 13 and later would not have an effect on it because the Calculator already has a darkish theme, and Good Invert does nothing to the theme both. Nevertheless, you would use Traditional Invert and Colour Filters to make it look the way you need. For Traditional Invert, within the “Accessibility” preferences, go to:

  • Show & Textual content Dimension –> Traditional Invert (iOS 13 and later)
  • Show Lodging –> Invert Colours –> Traditional Invert (iOS 12 and older)

For Colour Filters, within the “Accessibility” preferences, go to:

  • Show & Textual content Dimension –> Colour Filters (iOS 13 and later)
  • Show Lodging –> Colour Filters (iOS 12 and older)

Traditional Invert modifications the look to an inverted coloration scheme, whereas Colour Filters offers you plenty of choices, from Grayscale to Crimson/Inexperienced to Inexperienced/Crimson and Blue/Yellow, and you’ll even tint the display screen with any hue. To make it extra helpful, add Traditional Invert and Colour Filters to the “Accessibility Shortcut” within the “Accessibility” preferences. Then, simply triple-click the Facet or Dwelling button to activate it when it Calculator, then do it once more when leaving Calculator.

Tip 15: Make a Shortcut to Auto-Change Calculator’s Colours

If you happen to just like the Shortcuts app, you should utilize it in iOS 14 and later to create an automation that may change Calculator’s coloration scheme each time you open the app, then return it to regular every time the app’s closed. I will not go over the method right here, however you may see find out how to construct automation in our full information. Beneath, you may see Traditional Invert in motion (left) and Grayscale (proper).

Tip 16: Open Calculator by Tapping Your iPhone

Apple launched Again Faucet in iOS 14, an accessibility function that allows you to double- or triple-tap the again of your iPhone Eight or later to set off an motion of your selection. To make it open up Calculator, you’ll create a brand new shortcut and add one motion: “Open App,” with “Calculator” being that app. Then, go to Settings –> Accessibility –> Contact –> Again Faucet. Select both “Double Faucet” or “Triple Faucet” and choose the shortcut you created. Now, everytime you faucet your iPhone, Calculator will open.

Tip 17: Set Up Superior Shortcuts

Whereas we’re on the subject of shortcuts, that brings us to our final tip. The Shortcuts app will allow you to construct nearly any trigger-action state of affairs, automation, or process, and the Calculator has just a few actions which you could incorporate into your workflows — ten to be exact. I will not go into find out how to use each since every may very well be a complete article, however I am going to embrace their descriptions.
