Order of Operations -5th Grade

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The common acronym to remember this is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What should be solved first in the expression 8 - (12 ÷ 3) + 2?

Back

The division inside the parentheses, which is 12 ÷ 3.

Front

In the expression 12 - 4 x 2, which operation should be performed first?

Back

Multiplication (4 x 2) should be performed first.

Front

What is the result of the expression 8 - 4 + 3?

Back

The result is 7.

Front

Why are parentheses important in order of operations?

Back

Parentheses indicate which operations should be performed first, overriding the standard order of operations.

Front

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

Back

The result is 16, because you solve the parentheses first (5 + 3 = 8) and then multiply by 2.

Front

How do you handle multiplication and division in an expression?

Back

Multiplication and division are performed from left to right, depending on which comes first in the expression.

Front

What is the first step in solving the equation 8 - 4 + 3?

Back

The first step is to perform the subtraction: 8 - 4.

Front

What is the difference between addition and multiplication in terms of order of operations?

Back

Both addition and multiplication are performed from left to right, but multiplication is prioritized over addition.
