# Modular Arithmetic (mod)

If you type in "mod" this will allow you to use the mod function.

So, for example mod(x,2) will show you the remainder of x after dividing by 2. You can also use just numbers with the mod function. For example, mod(6,4) will show the remainder of 6 divided by 4 and output 2 in the expression list as the answer. If you click the FUNCTIONS key on the Desmos keypad, you'll find more supported functions in the tabs.

by Modular Arithmetic you mean modulo operation, there is a difference:

also, is there a Modular arithmetic in desmos (by the wikipedia's definition)?

Okay. I have some problems with desmos's mod function. sometimes it will tell me that the mod of the number I plugged in is GREATER than the number I used for the Modifier. Sometimes so large having to using scientific notation. for a modifier of 25.

701878, can you show an example? like "3=mod(x,2)", and mod takes 2 values not one, it wont work with one, i say this because: "mod of the number I plugged in"
