How do you add positive and negative numbers?

Answer 1

you subtract the negative from the positive

Answer 2

10+-6= +4
-10+-6= -16
-10+6= -4
if the same just add and use negative or positive sign
if two different signs subtract the numbers and use the sign that the number is greater on

Answer 3

Given two numbers with different signs, subtract the smaller number from the larger number and take the sign of the larger number.

7 - 9 = - 2
-7 + 9 = 2 (or + 2)

Answer 4

this is how u add positive and negative numbers for instince if u have -7+9 ok since nine is teh bigger number and its positive then that means that the answer will be postive ok anyways if teh sinbols are diffrent you subtract and if there the same u add so since there diffrent u say 9 - 7 = 2 and since i said that its gona be positive then that means that its positive 2 but if teh nine was negative and teh seven was positive then that means that the answer would of benn............................................ -2

Answer 5

well
negative numbers are riverses of positive numbers that you see :
14 -> -(14) -> -14 => 14 + (-14) = 14 - 14 = 0
so we have 2 numbers a,b (a>b>0) theres -(b) = -b
when you want to add -b to a you do this:
a>b => a=b+c => a + (-b) = b + c +(-b) = b + (-b) +c = b - b + c =0 +c = c => a+(-b)=a-b=c

Answer 6

collect all positive numbers together... add them...to get, say A

collect all negative numbers together... add them...to get, say B

if A>B, then result = (A - B)

if B>A, then result = - (B - A)

you know what A=B means...

Answer 7

Subtract.

Answer 8

numbers with same sign you add and then take the common sign,numbers with differnt signs you subtract and take the greater sign.

Answer 9

subract

ex.) 7+ (-4)= 3

Answer 10

on top of all of that here is a little more help. when you have two signs going together (ie 3+(-4)) you can use this legend.
(-)(-) = +
(-)(+)= -
(+)(-)= -
(+)(+)= +
