ACE 4.1 Order of Operations

Students worked all together today with Sima, and we discussed the order of operations, the order in which you do operations when computing the answer in a math sentence. Here is a helpful mnemonic:

Please
Excuse
My
Dear

Sally

or PEMDAS.

1. Parentheses
2. Exponent
3. Multiplication
& Division (whichever of these 2 comes first when going left to right)
4. Addition
