Math-positive and negative?

Question

Anyone know the rules for positives and negitive integers???

Answer 1

cant really help you cause there is too much to type
try yahoo math or homework help

Answer 2

Positive + positive = positive
example:
2+2=4
Positve + neg= depends on the higher #
example:
2+-2=0 or you can write it this way...
2-2=0

2+-4=-2
or
2-4= -2

Multiplication

pos x pos= pos
posx neg= neg
negx pos= neg
negx neg= pos

example:
-2 x -2 x 4 = 16
why? because -2 x -2 is 4 and 4 x 4 is 16.

If you need more help, please ask me. I can help and have some very useful websites that might help you.
By the way, an integer is just another word for number!
Good luck!

Answer 3

I'm assuming you are adding, subtracting, multiplying, etc..

Adding
Same signs.....Add and keep the sign
Different...subtract the two numbers and keep the sign of the larger number w/o looking at the signs
ex: 6+-7= -1

Sub
Change the - sign to addition and the second integer to its opposite
Follow rules for addition after

Mult and Dividing
Mult or Divide
Same signs = a positive answer
Different Sign= - sign

Answer 4

neg times neg = pos
pos times pos = pos
neg time pos = neg
subtracting a pos = adding a neg
subtracting a neg = adding a pos
I think that covers everything.

Answer 5

oaky...

addition::

positive+negative=subracting

postive+positive= positive

negative +negative=negatve



subractracting:

postive - negative= postive + postive

negative-negative= negative+ postive
