do you know how to use PEMDAS?
OpenStudy (lifeisadangerousgame):
Parentheses Exponents Multiplication Division Addition Subtraction We have parentheses in this problem so add 21 and 6 together to get 27. now we have multiplication so multiply 2 and 9 together to get18. so now we have [27 - 32] divided by 18. Subtract 32 from 27 to get -5. Now we have -5/18. I believe that is right.
