## What is Regular Division?

## What is Modular Division?

**only**the

**remainder**. Its symbol is: mod. Say you were doing 9 mod 4, after calculating that 4 goes into 9 twice, there is still 1 remaining. Your answer is 1.

9 mod 4

4 * 2 = 8

9 - 8 = 1

The answer is 1

## What is Integer Division?

Integer division is the opposite of Modular division. Instead of making the remainder the answer, it

**only**contains the**whole number**in its answer. The symbol is \. So if we used 9 \ 4 again, once you found out that 4 only goes into 9 twice, you would just put 2 as the answer. You don't even have to move on because the remainder is unnecessary in integer division.9 \ 4

4 * 2 = 8

9 - 8 = 1

The answer is 2

An acronym for the order of operations is Please Excuse My Dear Aunt Sally. It stands for parentheses first, exponents second, multiplication third, addition fourth, and subtraction last.
