when you add two positive integers the answer is always positive
when you add two negative integers the answer is positive
when you add one negative and on positive integer, the answer is negative
subtracting two negative numbers gets a negative answer
subtracting two positive numbers- the answer depends
subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
adding and subtracting integers is when you add and minus 2 numbers
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
there are no algorithms for subtracting algorithms!!!
Integers are whole numbers, both positive and negative. Therefore, adding and subtracting integers would be adding and subtracting whole numbers. Examples: 8+2 -8+2 8-2 -8-2
I would think that the commonality of adding and subtracting integers is that the answer itself will always be an integer. In other words, the answer is always gonna be a "whole number".
adding, subtracting, multiplying, dividing
Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.
4/9 - 6/36
No- adding negative numbers is like adding positive numbesr , except the answer is negative.
Let x and y be two integers. x - y = x + (-y)
