Answer: 1
Explanation:
Use PEMDAS to understand what to do first.
1. We do not have any Parentheses, so we can skip that.
2. There are no Exponents, so we can skip that too.
3. We do have Multiplication and Division, lets solve,
When solving multiplication and division, you do it in order of whichever comes first in the equation. Here, multiplication comes first.
3 · 6 = 18.
Now we divide.
18 / 2 = 9.
Lets look at PEMDAS again.
4. Addition and Subtraction, we have that so lets solve,
When solving addition and subtraction, you do it in order of whichever comes first in the equation. Here, addition comes first because there is no subtraction.
-8 + 9 = 1 1 is our answer.
We can check by switching the numbers around using the commutative property.
9 - 8 = 1.
Our final answer, is 1
