Negative 15 plus positive 20 equals 20 minus 15, which equals 5.
The answer is -5.
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
-20 -(-5) = -15 ie -(-5) = +5 therefore -20 +5 =15 (two double minuses = a positive)
115
If you add a positive number, another positive number, and a negative number, you can get anything - the result may be positive, negative, or zero. It all depends on the magnitudes of the numbers involved. For example: 10 + 10 - 1 = 19 (positive) 5 + 5 - 10 = 0 (zero) 5 + 6 - 20 = -9 (negative)
