Order of Operations 6.7A

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 acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does the acronym 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 step must be done first in the expression 5 + (3 x 2)?

Back

The first step is to perform the operation inside the parentheses: (3 x 2) = 6.

Front

In the expression 4 + 2^3, what is the value of the exponent?

Back

The value of the exponent is 3, which means 2 is multiplied by itself 3 times: 2 x 2 x 2 = 8.

Front

What is the result of the expression (6 - 2) x 5?

Back

The result is 20. First, calculate (6 - 2) = 4, then multiply by 5: 4 x 5 = 20.

Front

How do you simplify the expression 12 ÷ (2 + 2)?

Back

First, calculate the expression in parentheses: (2 + 2) = 4. Then divide: 12 ÷ 4 = 3.

Front

What is the value of 3^2?

Back

The value of 3^2 is 9, since 3 x 3 = 9.

Front

What is the result of the expression 8 - 3 + 2?

Back

The result is 7. First, perform the subtraction: 8 - 3 = 5, then add 2: 5 + 2 = 7.

Front

Which operation should be performed last in the expression 10 + 2 x 3?

Back

The last operation to perform is addition. First, multiply: 2 x 3 = 6, then add: 10 + 6 = 16.

Front

What is the simplified result of 5 + (2 x 3) - 4?

Back

The simplified result is 7. First, calculate (2 x 3) = 6, then: 5 + 6 - 4 = 7.
