Order of Operations - 5th grade

Front

What is the order of operations?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed in 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

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

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

Back

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

Front

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

Back

The result is 33.

Front

What is the result of simplifying (2 + 2) x 2 - 1?

Back

The result is 7.

Front

What does 'parentheses' mean in the order of operations?

Back

Parentheses are symbols used to group numbers and operations together, indicating that the operations inside should be performed first.

Front

What is an example of an expression that uses all parts of the order of operations?

Back

An example is: 2 + 3 x (4 - 1)².

Front

What is the first step in solving the expression 4 + 6 ÷ 2?

Back

The first step is to perform the division: 6 ÷ 2.

Front

What does 'exponents' mean in the order of operations?

Back

Exponents indicate how many times a number is multiplied by itself, for example, 2² means 2 x 2.
