lynfran · Answer

simplify

anonymous · Answer

anonymous · Answer

i don't think thats right

lynfran · Answer

yea correct

anonymous · Answer

supernaturallvr24 · Answer

I got -13

anonymous · Answer

could you please help and show me how to solve it?

lynfran · Answer

really https://www.symbolab.com/solver/step-by-step/-%5Cleft(2-%5Cleft(-1%5Cright)%5Cright)%5E%7B2%7D-3%5Cleft(4%5Cright)/?origin=enterkey

supernaturallvr24 · Answer

@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)!

supernaturallvr24 · Answer

Hope that explains it!!

lynfran · Answer

o i see it was just the (-1)^1 and not the entire bracket lol

supernaturallvr24 · Answer

Yeah :) glad I could help!

anonymous · Answer

could you please show step by step so i can write it out

supernaturallvr24 · Answer

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?

lynfran · Answer

no (-1)^2= positive 1

anonymous · Answer

the way you wrote it out is not in the order i have to show my work in

anonymous · Answer

its confusing me

lynfran · Answer

$$-(2-(-1)^2)-3(4)$$$$-(2-1)-12$$$$-(1)-12$$$$-13$$

anonymous · Answer

@LynFran thank you so much!

supernaturallvr24 · Answer

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.

lynfran · Answer

no u need to put brackets (-1)^2

lynfran · Answer

negative # times a negative #= positive #

supernaturallvr24 · Answer

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.

supernaturallvr24 · Answer

I guess that is true though.

supernaturallvr24 · Answer

Either way it still equals (-13)

lynfran · Answer

yea thanks for high-lightening that

supernaturallvr24 · Answer

No problem :)
