Multiples of particular number/value

Hi!

How do I check if a value (say of a global variable) is a multiple of a particular number?

For example, I'd like after every 5 turns for the game to give the player extra lives etc.

I'm thinking : compare if the global variable divided by 5 is equal to an integer, then add 1 life. But how do I write this as an expression?

Thanks for any suggestions!

Create a global variable called Turns

At the end of each turn add 1

Compare global Variable Turns = 5 then add 1 life, and set global variable to 0

Thank you so much- I love the simplicity of your solution!

Simple is always better

if turns % 5 = 0
