P- operations in the parentheses go first

E- exponents second

M- multiplication third *

D- division third *

S- subtraction fourth **

There is a second rule- go from left to right after you've done the parentheses and exponents.

*- Multiplication and division, either one can go first depending on which operation is closest to the left.

**-Addition and subtraction, either one can go first depending on which operation is closest to the left.

Example:

5*(7)/2+32 Do the exponent 32

5*(7)/2+9 Since 5*7 is closest to the left, do that instead of dividing by 2

35/2+9 Divide by 2
