Evaluate the expression by using the given values of the variables.

Order of operations tell us that we do multiplication and division first in the order we get to them, and then addition and subtraction after.  24/4*3-6/3+8.  We'll divide 24 by 4 to get 6, but then we immediately have to multiply 6 times 3 to get 18.  Then move down to 6 divided by 3 to get 2.  So what we have now is 18 - 2 + 8 which is 24.
