Ignore the signs and subtract the smaller number from the larger one.
You subtract the smaller from the larger.
None, because the set of integers and the set of whole numbers is the same.
Let x and y be two integers. x - y = x + (-y)
if the signs are the same you must add 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.
The answer will have the same sign as the number with the larger magnitude.
(-10) - (-5) = (-5) when subtracting a negative number from another negative number if the first number is larger that the second number then you just subtract the to numbers. don't worry about the signs just subtract the numbers when your done put the sign of the first number on again.
"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."
