Maybe because you're finding the "difference" between the two numbers. We could also question why the answer to an addition problem is called sum.
Well, 'sum'body said that's what they should be called a long time ago, that's why we're using that term to call them now.
<span>A word problem that can be modeled by addition of two negative numbers integers is given as followed.
Evans and Irvin are standing at the same spot. Evans took 7 steps backwards and another 7 steps backward, what is the current position of Evans relative to where Irvin is standing?
To solve the above, we note that Evans </span><span>took 7 steps backwards and another 7 steps backward, thus his current position relative to Irvin is given by (-7) + (-7) = -7 - 7 = -14.
Therefore, Evans is 14 steps backwards relative to where Irvin is standing.

Answer:
180
Step-by-step explanation:
8x15 is 120. The formula to find the area of a right triangle is base x height divided by two.
120/2 is 60
60x3 is 180.

Answer:
Y = 6
X = 24
Step-by-step explanation:
2x -5y = 16
(x -2y =5)*2
_______________
2x -5y = 16
2x - 4y = 10
_______________
(2x -5y = 16) - (2x - 4y = 10)
_______________
0x -y = 6
_______________
y =6
_______________
Replacing in equation 1:
2x - 5(6) = 16
so, 2x = 16 + 30
2x = 48
x = 24
