You are essentially subtracting the negative number several times — and as seen above, subtracting negative numbers results in a positive equation.
What does subtracting positive and negative numbers mean?
Subtracting positive and negative numbers means that you add the opposite numbers, or additive inverse. Change the subtraction sign to addition and change the sign that follows to its opposite. Then follow the steps for addition. For example:
What happens when you see a negative and a minus sign together?
A good tip is that whenever you see a negative sign and a minus sign together, such as in 9 - (-7), immediately make them positive signs. The negative signs cancel each other out , and the equation becomes an addition problem.
When using positive and negative numbers, do you use the rules for signing numbers?
When using positive and negative numbers, you use the rules for signed numbers (numbers with positive or negative signs in front of them). Also known as operations for signed numbers, these steps can help you avoid confusion and solve math problems as quickly — and correctly — as possible.
What is a number higher than zero called?
Numbers higher than zero are called positive numbers , and numbers lower than zero are negative numbers. That means they fall at either side of the number line. However, just because they're on the same line doesn't mean they follow the same rules! Keep reading for a list of the basic rules for using positive and negative numbers in math.
