    @allymack OK so the problem was -(2-(-1)^2-3(4). First thing to remember is use P.E.M.D.A.S. So (-1)^2= (-1). Next. 3*4=12. After that is -(2-(-1)=(-1). So (-1)-12=(-13)!

    OK. Step 1: (-1)^2=(-1) Step 2: 3*4=12 Step 3: -(2-(-1)=(-1) Step 4: (-1)-12=(-13) [Another way to write this is 1+12=13 then make it negative. How's that?

    no (-1)^2= positive 1

    Nope, if you put it into a calculator then it equals (-1). Well, it's also depending on HOW you put it into the calculator.

    negative # times a negative #= positive #

    The (-) in front of the 1 on my calculator is a negative sign, the button for that is next to the period button on there.

    Either way it still equals (-13)
