Order of Operations - 5th grade

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 operation do you perform first in the expression 3 + 4 x 2?

Back

You perform multiplication first, so 4 x 2 = 8, then add 3.

Front

Simplify the expression: 5 + 2 x 3.

Back

5 + 6 = 11.

Front

What is the result of 8 - 3 + 2?

Back

You perform addition and subtraction from left to right: 8 - 3 = 5, then 5 + 2 = 7.

Front

What is the difference between (3 + 5) x 2 and 3 + (5 x 2)?

Back

(3 + 5) x 2 = 16, while 3 + (5 x 2) = 13. They are not equal.

Front

What should you do first in the expression 10 - (2 + 3) x 2?

Back

You should calculate the expression inside the parentheses first: 2 + 3 = 5.

Front

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

Back

First, calculate inside the parentheses: 3 + 1 = 4. Then, 2 x 4 = 8. Finally, 6 + 8 = 14.

Front

In the expression 4 x (2 + 3) - 5, what do you calculate first?

Back

You calculate the expression inside the parentheses first: 2 + 3 = 5.

Front

What is the result of 12 ÷ 4 + 3 x 2?

Back

First, divide: 12 ÷ 4 = 3. Then, multiply: 3 x 2 = 6. Finally, add: 3 + 6 = 9.
