1. If a negative number is added to the same number in positive, the answer will be 0. (-n)+n=0 2. If 0 is added to a negative number, the answer is the negative number. 0+(-n)=(-n)
1. If a positive number is added to a negative number, the number will only be 0 if the two numbers have the same digits.An example is: positive 1+(-1)=0
2. The sum of two negative integers is a negative integer.An example is: (-3)+(-5)=(-8) Rather than the number reduce to be a smaller value, the number increases to a bigger value in the terms of negative.
I'm not sure if this counts:
ReplyDelete1. If you add 2 even numbers or 2 odd numbers, the sum would be even
2. If you add 1 odd number and 1 even number, the sum would be odd
1. If a negative number is added to the same number in positive, the answer will be 0.
ReplyDelete(-n)+n=0

1. The sum of the same numerical part of a negative number and a positive number will be 0. Eg.(-y)+y=0 OR (-3)+3
ReplyDelete2. The sum of two different negative numbers always results in a negative number. Eg, (-y)+(-x)=(-y)+(-x) OR (-4)+(-5)=(-9)
*numerical part meant to be numerical value
ReplyDelete(-n)+(-y)=(-n)-y
ReplyDeleten+y=n+y
n-(-y)=n+y
