What is minus minus equal to?
Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, – (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 – –4.
How do you minus a minus number?
Subtracting a negative number is the same as adding a positive number — that is, go up on the number line. This rule works regardless of whether you start with a positive number or a negative number.

Does minus mean subtraction?
Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign, −. It is also not associative, meaning that when one subtracts more than two numbers, the order in which subtraction is performed matters.
Why is minus minus a plus?
The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again. Even in such general, non-numerical contexts, the property that the product of two negative things is positive still holds.
Why when you subtract a negative is positive?
Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.
Is minus a real word?
