Nope.
When they say a = -1, the meaning is that symbol a represents the number -1.
You replace the symbols in the given expression with the numbers they represent.
If we replace symbol a with the number -1, then the given expression looks like this:
-11(-1)(-bc)
Next, you replace symbol b with its given value, and you replace symbol c with its given value, and THEN you multiply the resulting numbers together. (Don't forget the negative sign in front of number b.)
PS: Next time, please state what you've tried or thought about. It's difficult to tutor people who don't say much. Cheers :cool:
