While looking at this problem, it is apparent that we will need to use Order of Operations to solve it, also known as PEMDAS (Please Excuse My Dear Aunt Sally)
Parentheses
Right off the bat, we can see that there is a pair of parentheses in this expression, so we must solve what's in those first.
3 * 63 = 189
Exponents
There are no exponents in this problem to worry about, so we can move on.
Multiplication/Division
At this point, the expression looks like this:
189 - 16 * 134
When there is a step that involves multiplication in the expression, that automatically gets taken care of first.
16 * 134 = 2144
Addition/Subtraction
Finally, we can solve the expression.
189 - 2144 = -1955
(3 * 63) - 16 * 134 = -1955
Hope that helped =)
