Order of Operations - 5th grade

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that tells you the correct sequence to evaluate a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often remembered by the acronym PEMDAS.

Front

What does PEMDAS stand for?

Back

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

Front

What should you do first in the expression 3 x (4 + 5) - (6 + 7)?

Back

You should first solve the expressions inside the parentheses: (4 + 5) = 9 and (6 + 7) = 13.

Front

Simplify the expression: (9 x 2) - 2 x 4

Back

First, calculate (9 x 2) = 18, then calculate (2 x 4) = 8. Finally, 18 - 8 = 10.

Front

What is the result of 3 x (5 + 7) - 2?

Back

First, solve the parentheses: (5 + 7) = 12. Then, calculate 3 x 12 = 36. Finally, 36 - 2 = 34.

Front

Does (3 x 9) + 2 equal 3 x (9 + 2)?

Back

No, (3 x 9) + 2 = 27 + 2 = 29, while 3 x (9 + 2) = 3 x 11 = 33.

Front

What is the value of 13 + (5 x 4)?

Back

First, calculate (5 x 4) = 20. Then, 13 + 20 = 33.

Front

In the expression 3 x (5 + 7) - 2, what operation do you perform first?

Back

You perform the addition inside the parentheses first: 5 + 7.

Front

What is the result of 3 x (4 + 5) - (6 + 7)?

Back

First, solve the parentheses: (4 + 5) = 9 and (6 + 7) = 13. Then, calculate 3 x 9 - 13 = 27 - 13 = 14.

Front

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

Back

The first step is to perform the multiplication: 3 x 4 = 12, then add 2 + 12 = 14.
