Minus a negative means you add: 10.3 - -5 = 10.3 + 5 = 15.3

To find the additive inverse of ANY number, add a minus sign. (If the number already has a minus sign, take the minus sign away to get the additive inverse.)
It could be any number greater than the minus. For example: -4 + 1 = -3 -4 + 2 = -2 -4 + 3 = -1 -4 + 4 = 0 -4 + 5 = 1 -4 + 6 = 2 and so on.
X2 - 4X - 5 = 0 easy factor, what two factors of - 5 add up to - 4 (X + 1)(X - 5) X = - 1 ------------- X = 5 --------------

There are two different ways. You subtract a whole number from it: Example: (-1) - 4 = (-5). Or, you can add another negative number: Example: (-1) + (-4) = (-5) No, actually add the absolute value. For example 4 -(-1) = 4 + 1 = 5
minus 4 is bigger because minus 5 is further away from naught that minus 4 is
Minus a negative means you add: 10.3 - -5 = 10.3 + 5 = 15.3
-5 minus 4 is -9.
-4 basically you take 5 from one!

a negative minus a positive is like addition, you take the negative add the positive, then make that number a negative.Example-5 - 4add them5 + 4= 9make that number a negative= -9
4 - 5 + (-2) = -3
To find the additive inverse of ANY number, add a minus sign. (If the number already has a minus sign, take the minus sign away to get the additive inverse.)
-4-(-9)+(-5) = -4+9-5 = 0
