You subtract the smaller from the larger.
None, because the set of integers and the set of whole numbers is the same.
Ignore the signs and subtract the smaller number from the larger one.
no
Let x and y be two integers. x - y = x + (-y)
(-4)-(-9)=5

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.
"Delta" is often used to mean "the difference" between two numbers, and that is the same as subtracting. When you subtract, the answer is called the "difference."
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.
