Question 578003: I am trying to help my son with his math homewoork and I am a little rusty, any help would be nice.
((8*1000)+(4*1000)+(2*10)+(8*1))
(-(3*1000)+(6*100)+(6*10)+(1*1))
________________________________
a) (4*1000)+(2*100)+(4*10)+(7+1)
b) (4*1000)+(7*100)+(6*10)+(7+1)
c) (5*1000)+(8*100)+(6*10)+(7*1)
d) (5*1000)+(2*100)+(6*10)+(7*1)
An explaination would be greatly appreciated!
You can put this solution on YOUR website! I'm guessing there is a typo and it's supposed to be 4*100.... assuming that:
((8*1000)+ (4*100)+(2*10)+(8*1))
(-(3*1000)+(6*100)+(6*10)+(1*1))
____________________________
multiply it out and distribute the negative:
8000 + 400 + 20 + 8 = 8428
- (3000 + 600 + 60 + 1) = - (3661)
8428 - 3661 = 4767, which can be re-written as
4000 + 700 + 60 + 7 or
(4*1000)+(7*100)+(6*10)+(7*1); answer B
