When adding integers, you need to look at the number, and see + or - to determine what you should do to raise or lower your number. Ex. -98 + +3 = - 95. Ex. +98 + -3 = +95. Ex. +900 - -95 = +995. Ex. -900 - +95 = -995. the end

Subtracting Integers is just like subtracting normal numbers! Next, adding integers!

When you add integers make sure you look at the number to see if they are positive or negative. When you add a positive number and a negative number it is pretty much just subtracting the two numbers. Ex. 6+-3=3
But when you subtract a negative number from a positive number it is just adding the two numbers Ex.2--3=5
When adding two positive numbers you just add them together.Ex.1+7=8
That's how you add and subtract integers!;)
