1. PEMDAS and Simplifying
By Cole Funk

2. PEMDAS
PEMDAS is an acronym that tells you what order to follow when doing mathematical operations
Parentheses: if there are parentheses, work inside those first
Exponents: next, take care of any exponents
Multiplication and Division: before adding and subtracting, multiply and divide
Addition and Subtraction: Last, add and subtract
Please excuse my dear aunt Sally

3. Let’s Practice!
7(13 - 8)
24 - (32 + 1)
2(30 – ( ))
(2(3+4)2 + 4)) – 4x7 + 42
9n – 2(n + 5) +3 n

4. Get rid of as many parentheses as possible Combine like terms
Rules for simplifying
Get rid of as many parentheses as possible
Combine like terms
Order is standard form

5. 2(x + 4) + 3(x – 5) - 2y 2x(x – 3) + 6(32) – 2(2 – x)
Let’s Practice!
2(x + 4) + 3(x – 5) - 2y
2x(x – 3) + 6(32) – 2(2 – x)
(3x)2 - 16x + x(x – 2)
