addition and subtract in integers
It is important to add and subtract integers: to get a new integer value in mathematics .
to subtract an integer, add its opposite or additive inverse.
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!
negetive integers are not closed under addition but positive integers are.
Subtract and the Keep the sign of the one that has more
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 the number with the smaller absolute value from the other. Give the answer the sign of the number with the larger absolute value.
you can add subtract multiply and divide them.

49+50+51=150 General rule for this kind of question: divide the number you're trying to obtain (150) by the number of integers you're allowed (3), and then simply add one and subtract one until you have the specified number of integers.
negetive integers are not closed under addition but positive integers are.
add, subtract, multiply, divide
Subtract the smaller from the larger.
