This means that, for example:
15 - 5 = 15 + (-5)
15 - (-5) = 15 + 5
Knowing this relationship can both help you do the actual calculations, and assist you in solving equations.

How can you use addition of integers to subtract integers?
Subtracting an integer is the same as adding the additive inverse. In symbols: a - b = a + (-b), where "-b" is the additive inverse (the opposite) of b.
How is subtracting integers like adding integers?
It's pretty much the exact same. Subtracting is the same as adding a negative number. Foe example, five minus three is the same as five plus negative three.
Is adding integers and subtracting integers are the same?
Let x and y be two integers. x - y = x + (-y)
How is adding to negative integers the same as and different from subtracting two positive integers?
No- adding negative numbers is like adding positive numbesr , except the answer is negative.
When subtracting and adding integers how do you decide what the sign of the answer will be?
The answer will have the same sign as the number with the larger magnitude.

Why does subtracting a number give the same result as adding its opposite?
adding its opposite?

What is the rule for subtracting integers with the same signs?
if the signs are the same you must add its opposite.
When subtracting and adding integers how do you decide what the sign of the answer will be?
The answer will have the same sign as the number with the larger magnitude.
How are adding subtracting decimals different from multiplying them?
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.
What are the rules in adding subtracting multiplying and dividing integers?
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.
How are adding and subtracting fractions similar?
Subtracting a fraction is the same as adding its negative.
Rules for adding and subtracting integers?
ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.
Is adding different integers the same as adding integers?
Yes.
