Prime? - a tool for math

INTRO

· Prime lets you work with prime numbers in 4 different ways: Checker, List, Factorize, and Randomize.


SOME TIPS

· In addition to using the Randomize page of the app, you can use Siri to get random primes. To do so: open Settings > Siri & Search > All Shortcuts > Get random prime, then record the phrase you want to tell Siri whenever you want Siri to get you a random prime.
Note: In order to set up Siri Shortcuts you must first have generated at least 1 random prime in the app itself, using the 'Randomize' button. Also, if the app is already showing a random prime, make sure you close the page, using the top left 'Done' button, before asking Siri for a new prime.

· If a page is calculating, switching to a different page will not interrupt that.

· You can tap on the top right button to share or save a result.

· You can turn the app's sounds on or off in the app's settings. With the app's sound set to 'On', sounds play when you find a prime number, or if you accidentally enter invalid text in a textfield.

· You can set the app's theme to dark or light in the app's settings.

· You can choose whether results use the thousands separator in the app's settings.


CHECKER

· Check whether any number is prime, and if it is not, see a number it is divisible by.

· Type or paste a number, then tap on 'Check'.

· Find a prime number to hear a satisfying 'Choo'!


LIST

· List all prime numbers in a given range: for example, type 1 in the first text box, 10 in the second, then tap on List, and you will get 1, 2, 3, 5, and 7.


FACTOR

· Get the prime factors for a number: for example, type 12, and you will get 2, 3, and 3.


RANDOM

· Get a random prime of a size of your choice.
· This can be done using Siri Shortcuts as well (see 'Some Tips' above for instructions).
