Operations with Integers
By: Melissa and Sebastian
If the problem is 4+4=? and the digits are positive it will always be positive so its 4+4=8.
-8+4=? if one digit is negative and the other is positive it will always be negative so its -8+4=-4.
-9+-3=? if you have 2 negative numbers the answer will always be negative so its -9+-3=-12.
If both signs are positive it will always be positive, 14 - (-6) = 20.
If both signs are negative it will always be negative. -12-6=-18.
Unlike signs like -4+3=? will always be negative, so the answer would be -1.
The product of a positive integer and a negative integer is a negative integer. -3*5=-15.
The product of two negative integers is a positive integer. -6*-5=30.
If you have two positive integers is a positive integers 3*4=12.
If we have a negative and a positive for example -12/4=? the answer will always be negative so we divide and the answer is -3.
If we have negative divided by negative the answer will always be positive for example -4/-4= 1.
If we have positive divided by negative the answer will always be negative, ex. 8/-4= -2.
