Front

What is the Order of Operations?

Back

A set of rules that tells us the correct sequence to evaluate 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

What do you do first in the Order of Operations?

Back

Always solve expressions inside Parentheses first.

Front

What is the result of 9 + 2 x 4?

Back

17 (First multiply 2 x 4 = 8, then add 9 + 8 = 17).

Front

What is the result of 17 + 2 x 5?

Back

27 (First multiply 2 x 5 = 10, then add 17 + 10 = 27).

Front

What is the result of 22 - 6 x 3?

Back

4 (First multiply 6 x 3 = 18, then subtract 22 - 18 = 4).

Front

What is the result of (12 - 5) x (3 + 1)?

Back

28 (First solve inside the parentheses: 12 - 5 = 7 and 3 + 1 = 4, then multiply 7 x 4 = 28).

Front

What is the result of 3 + 5 x 6?

Back

33 (First multiply 5 x 6 = 30, then add 3 + 30 = 33).

Front

What is the role of Multiplication in the Order of Operations?

Back

Multiplication is performed before Addition and Subtraction.

Front

What is the role of Parentheses in the Order of Operations?

Back

Parentheses indicate that the operations inside them should be performed first.
