# I don't understand the modulus operator. how do you perform this on a calculator? how are you getting the answers?

I don't understand the modulus operator. how do you perform this on a calculator? how are you getting the answers?

Hi Joe,

The modulus is the remainder from a division operation. So if you have 15/5, you will get 3 and no remainder. The modulus is 0 here. Or if you have 18/4, you will get 4 and a remainder of 2. The modulus here is 2.

For example, if you had this: 5 * 2 + 9 % 4 + 8 / 4 Then you have 5 * 2 = 10, 9 % 4 = 1, 8 / 4 = 2 or 10 + 1 + 2 and your answer will be 13.

Cheers!

thank you! I also discovered that if you're doing this on a calculator it will give you a decimal. to convert to the remainder, your multiply the decimal to the divisor. Thanks!
