What is the first step in solving the expression 3 x 48 / (15 - 3)?

Back

The first step is to solve the expression inside the parentheses: 15 - 3 = 12.

Front

In the expression (19 - 7) ÷ 4 + 11, what should you solve first?

Back

You should solve the expression inside the parentheses first: 19 - 7 = 12.

Front

What is the result of 3 + 2^4?

Back

The result is 19, because 2^4 = 16 and then 3 + 16 = 19.

Front

Identify the error in the calculation: 5 - 3 + 2 = 5 - 5 = 0.

Back

The error is that addition was done first instead of subtraction.

Front

What is the first operation to perform in the expression 3 + 4 x 6 - 4?

Back

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

Front

What is the order of operations in mathematics?

Back

The order of operations is PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.

Front

Why is it important to follow the order of operations?

Back

It is important to follow the order of operations to ensure that mathematical expressions are solved correctly and consistently.

Front

What is an example of an expression that requires the use of PEMDAS?

Back

An example is 2 + 3 x (4 - 1). You would solve the parentheses first, then multiplication, and finally addition.

Front

What is the value of 8 ÷ 2(2 + 2)?

Back

The value is 16. First, solve the parentheses: 2 + 2 = 4, then 8 ÷ 2 = 4, and finally 4 x 4 = 16.
