Front

What is the first step in the order of operations?

Back

The first step is to solve expressions inside Parentheses.

Front

What is the second step in the order of operations?

Back

The second step is to calculate Exponents.

Front

What do you do after solving Parentheses and Exponents?

Back

After solving Parentheses and Exponents, perform Multiplication and Division from left to right.

Front

What is the last step in the order of operations?

Back

The last step is to perform Addition and Subtraction from left to right.

Front

If you have the expression 3 + 5 × 2, what is the correct answer?

Back

The correct answer is 13, because you multiply 5 × 2 first, then add 3.

Front

In the expression (4 + 6) × 2, what do you solve first?

Back

You solve the expression inside the Parentheses first, which is 4 + 6 = 10.

Front

What is an example of an expression with an Exponent?

Back

An example is 2^3, which means 2 multiplied by itself 3 times (2 × 2 × 2 = 8).

Front

How do you handle Multiplication and Division in an expression?

Back

You handle Multiplication and Division from left to right as they appear in the expression.

Front

What is the difference between Addition and Subtraction in the order of operations?

Back

Addition and Subtraction are performed last, and they are also handled from left to right.
