Wednesday, Sept. 10 - Order of Operations
Objective: To understand and be able to use the order of operations.
Order of Operations is important. It tells you in what order to do multi-step problems. Without it, you could get different answers based on how you worked the problem.
We use the acronym PEMDAS
Paragraph
Exponents
Multiplication
Division
Addition
Subtraction
- P as the first letter means you complete any calculations in grouping symbols first.
- Next, look for exponents, E. Ignore any other operation, and take any numbers with exponents to their respective powers.
- Even though M for multiplication in PEMDAS comes before D for division, these two operations actually have the same priority. Complete only those two operations in the order they occur from left to right.
- Even though A for addition is in PEMDAS before S for subtraction, these two operations also have the same priority. You look for these last two operations from left to right and complete them in that order.
