Front

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

What do you do first in the expression 12 ÷ 3 x 4?

Back

Perform the division first: 12 ÷ 3 = 4.

Front

What is the result of 13 - 2 x 4?

Back

5 (because you multiply 2 x 4 first, then subtract from 13).

Front

What is the result of 10 + 15 ÷ 5?

Back

13 (because you divide 15 ÷ 5 first, then add to 10).

Front

What is the result of 7 - 4 + 4?

Back

7 (because you perform the subtraction and addition from left to right).

Front

What is the result of 24 ÷ 4 x 2?

Back

12 (because you divide 24 ÷ 4 first, then multiply by 2).

Front

In the expression 5 + (3 x 2), what do you calculate first?

Back

Calculate inside the parentheses first: 3 x 2 = 6.

Front

What is the result of (8 - 3) x 2?

Back

10 (because you calculate inside the parentheses first: 8 - 3 = 5, then multiply by 2).

Front

What is the result of 6 + 2 x (3 + 1)?

Back

10 (because you calculate inside the parentheses first: 3 + 1 = 4, then multiply by 2, and finally add 6).
