addition and subtract in integers
the addition of integers is when adding negative and positive integers
It is important to add and subtract integers: to get a new integer value in mathematics .
negetive integers are not closed under addition but positive integers are.
You can use them for counting, which is in fact addition. You can also use them for subtracion. Integers are natural numbers. This means you don't use decimals or fractions.

turn the subtraction sign into an addition sign and the 3 into a negative: 1+-3=-2

if they are two positive numbers, do it normally.If there is a negative and a positive, change it to addition and switch the SECOND integer sign. Only works with two integers in a subtraction question.Example: (-32)-(+2)= (-34) / (-32)+(-2)=(-34)

subtract divide multiply addition
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.
to subtract an integer, add its opposite or additive inverse.
you can add subtract multiply and divide them.
Because otherwise you would only know how to subtract and add with the same integers. Not a particularly useful skill unless just those integers turned up!
