What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Solve: 3 + 5 x 2

Back

13 (First, multiply 5 x 2 = 10, then add 3).

Front

Solve: (6 + 2) x 3

Back

24 (First, add 6 + 2 = 8, then multiply by 3).

Front

What is the first step in solving 4 + 3 x 2?

Back

Multiplication (3 x 2 = 6, then add 4).

Front

True or False: 5 + 2 x (3 + 1) = 13

Back

True (First, solve inside the parentheses, then multiply, and finally add).

Front

What is the second step in solving 8 - 2 + 4 x 3?

Back

Multiplication (4 x 3 = 12, then subtract and add).

Front

Solve: 10 - (2 + 3) x 2

Back

0 (First, solve inside the parentheses, then multiply, and finally subtract).

Front

What is an exponent?

Back

A number that shows how many times to multiply the base by itself.

Front

Solve: 2 x (3 + 5) - 4

Back

10 (First, solve inside the parentheses, then multiply, and finally subtract).
