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 abbreviated as PEMDAS.

Front

What operation do you perform first in the expression 2 + 8 x 3?

Back

You perform multiplication first, so 8 x 3.

Front

In the expression 3 x (5 + 7) - 2, what should you calculate first?

Back

You should calculate the expression inside the parentheses first, which is 5 + 7.

Front

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

Back

No, they do not equal the same. (3 x 9) + 2 = 29, while 3 x (9 + 2) = 33.

Front

What is the result of simplifying (9 x 2) - 2 x 4?

Back

The result is 10.

Front

What is the first step in solving 3 x (4 + 5) - (6 + 7)?

Back

The first step is to calculate the expressions inside the parentheses: (4 + 5) = 9 and (6 + 7) = 13.

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

If you have the expression 5 + 3 x 2, what do you calculate first?

Back

You calculate the multiplication first: 3 x 2 = 6, then add 5 + 6.

Front

What is the value of 8 + 2 x (3 + 1)?

Back

First, calculate inside the parentheses: (3 + 1) = 4. Then, multiply: 2 x 4 = 8. Finally, add: 8 + 8 = 16.

Front

In the expression 6 - 2 + 3, which operation do you perform first?

Back

You perform the operations from left to right, so you first do 6 - 2 = 4, then add 3 to get 7.
