√[(X2-X1)2+(Y2-Y1)2]minus a negative is plus a positive√[(5+3)2+(-2-4)2]plus a negative is minus a positive√(82-62)√(64-36)√28 or 2√7
Does a positive plus a negative equal a negative?

Why is the sum of a positive integer and a negative integer is always negative?
It isn't always negative. ... for example: -5 + 12 = 7 (a positive number) -5 + 2 = -3 (a negative number) -5 + 5 = 0 (neither negative nor positive) If the negative number has greater magnitude than the positive number, the sum will be negative If the positive number has greater magnitude than the negative number, the sum will be positive If the negative and positive numbers have the same magnitude, the sum will be zero.
What is the answer when you subtract a positive number and a negative number?
You know the saying two lefts don't make a right? Well, the opposite applies here. Two negatives indeed do make a positive. Say I have two numbers, 10 and -5, and I want to subtract the positive one from the negative one. 10 - (-5) <-- two negatives in a row become a positive. 10 + 5 = 15 You can verify this yourself by using a number line. The difference is visually the distance between two numbers on a number line. The distance from 10 to -5 is indeed 15.
What is the answer to negative fifteen divided by positive three?
