The answer can be negative, zero, or positive. For example: -15 + 20 + (-10) = -5 -15 + 20 + (-5) = 0 -15 + 20 + (-2) = 3
Equals positive or negative. Because minus a positiveequals plus a negative.(+15) - (+20) = (+15) + (-20)If you want to lear the rules, use a plus symbol between the parts of the operation.(+) + (+) = +(-) + (-) = -(+) + (-) = - or +Generally speaking, if just one number have a negative sign, the result can be both positive or negative.
-5 Here is a quick tip, when the negative number is larger, pretend it is positive and subtract the smaller one from it. Then just put the negative sign back on
17
-20 + 13 = -7
-1+20 = 19
-20 + 5 = -15
70
20
Negative 15 minus 5 can be solved by subtracting 5 from -15. This results in -20, as subtracting a positive number from a negative number increases the magnitude of the negative value. In mathematical terms, -15 - 5 = -20.
-20 -(-5) = -15 ie -(-5) = +5 therefore -20 +5 =15 (two double minuses = a positive)
