Question

How do you evaluate `15- 2^ { 3} + 3`?

Answer 1

The Value Is `10`.

Explanation:

Always take care of parenthesis or exponents first. Simplify `2^3`. See below:

`2^3=8`

Insert `8` back into the problem. See below:

`15-8+3=?`

Now we can simply combine all of this together to get our final answer.

`15-8=7`

`7+3=10`

According to PEMDAS (any other way that works for you is fine as well), we always do these steps IN ORDER:

• Parenthesis
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

Answer: `10`.
