Answer:
Do PEMDAS.
Explanation:
PEMDAS:
Parenthesis
Exponents
Multiplication/Division (whichever comes first in the equation)
Add/Subtract (same as there ^)
First, do 18 divided by six, since there are no parenthesis and no exponents, and Division is first.
Then, take the 3 you received from 18 divided by 6 and subtract the 2. (Because there is no more Multi/Divi and subtract is first.) You get 1.
Take the 1 and add 18.
Your answer is 19.
