The document discusses the order of operations known as PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. It provides the example equation 7 + (6 × 52 + 3) and step-by-step works through solving it following PEMDAS order: evaluating inside the parentheses first, then performing exponent operations, followed by multiplication and division from left to right, and finally addition and subtraction from left to right. The document also provides some sayings to help remember PEMDAS order.

1. S
Order of Operations
PEMDAS

2. What Do You Start With?
S When you are given an equation like this:
7 + (6 × 52 + 3)
What do we try to calculate first?

3. PEMDAS
S The order goes as follows:
S Parenthesis
S Exponents (Powers, Square Roots)
S Multiplication/Division
S Addition/Subtraction
S With multiplication/division, you do it left to right
S With addition/subtraction, you do it left to right

4. What’s the Answer?
S If we have this:
7 + (6 × 52 + 3)
S 7 + (6 × 25 + 3) Start inside Parentheses, and then use Exponents
First
S 7 + (150 + 3) Then Multiply
S 7 + (153) Then Add
S 7 + 153 Parentheses completed, last operation is an Add
S 160 DONE !
