Front

What is the first step in solving an expression using PEMDAS?

Back

The first step is to solve any operations inside Parentheses.

Front

How do you handle Exponents in PEMDAS?

Back

You calculate the value of the exponent before performing multiplication, division, addition, or subtraction.

Front

In the expression 6 + 3² x 4 - 2² ÷ 4, what do you calculate first?

Back

You calculate the exponents: 3² = 9 and 2² = 4.

Front

What is the result of 2²?

Back

The result of 2² is 4.

Front

In the expression 90 - 5² x 3, what operation do you perform after calculating the exponent?

Back

After calculating the exponent, you perform multiplication: 5² = 25, then 25 x 3.

Front

What is the value of 5² x 3?

Back

The value of 5² x 3 is 75.

Front

In the expression 63 ÷ 7 - 3 ⋅ 2 + 4, what is the first operation to perform?
