This is a pretty vanilla question testing whether we understand ordering.
- 00:28
In general, ordering goes like this:
- 00:31
Parentheses
- 00:32
Exponents
- 00:33
Then multiplication and division
- 00:34
Then addition and subtraction
- 00:37
And the process goes generally from left to right.
- 00:41
So since there are no parentheses or exponents here...
- 00:44
...we start with the multiplication and division.
- 00:47
The leftmost elements is the negative 4 times negative 5 -- that's the operation we do first.
- 00:52
So the answer is just C.
- 00:54
We have now proven ourselves as ordering masters.
