Order of Operations/ Numerical Expressions

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).

Front

What is the first step in solving the expression 9 + 4 ÷ [4 x (5 - 4)]?

Back

The first step is to solve the expression inside the parentheses: (5 - 4) = 1.

Front

How do you simplify the expression (16 - 6) x (2 + 4)?

Back

First, solve the expressions in the parentheses: (16 - 6) = 10 and (2 + 4) = 6. Then multiply: 10 x 6 = 60.

Front

In the expression 3 + 4 x 6 - 4, which operation should be performed first?

Back

The first operation to perform is multiplication: 4 x 6 = 24.

Front

What is the result of the expression 5 x (7 - 4) - 3 x 2?

Back

First, solve the parentheses: (7 - 4) = 3. Then calculate: 5 x 3 = 15 and 3 x 2 = 6. Finally, subtract: 15 - 6 = 9.

Front

Which expression represents 'double 12 and then add 78'?

Back

The expression is (2 x 12) + 78.

Front

What is the value of 4 x (3 + 5)?

Back

First, solve the parentheses: (3 + 5) = 8. Then multiply: 4 x 8 = 32.

Front

What is the result of the expression 8 + 2 x 5?

Back

According to the Order of Operations, first multiply: 2 x 5 = 10. Then add: 8 + 10 = 18.

Front

What is the first step in solving 12 - (3 + 2) x 2?

Back

The first step is to solve the expression inside the parentheses: (3 + 2) = 5.
