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.
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.
Let x and y be two integers. x - y = x + (-y)
No- adding negative numbers is like adding positive numbesr , except the answer is negative.
The answer will have the same sign as the number with the larger magnitude.

adding its opposite?
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.

if the signs are the same you must add its opposite.
The answer will have the same sign as the number with the larger magnitude.
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.
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.
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.
Subtracting a fraction is the same as adding its negative.
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.
