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.

What is the rule for subtracting and adding negative numbers?
When adding positive numbers, count to the right. When subtracting positive numbers, count to the left. When subtracting negative numbers, count to the right.
Why do negatives cancel out?
Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero.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.
Why do 2 negatives equal a positive?
Originally Answered: Talking logically, why does multiplying two negatives give you a positive? Because multiplication changes the sign of a number. In this case, it’s from positive to negative.
How do you subtract from a number?

How do you add 2 negative numbers?
Adding two negative numbers together? Just add the absolute value of each number together, put a negative sign in front, and you have your answer!
What are the rules of negatives?
The Rules:
| Rule | Example | |
|---|---|---|
| +(+) | Two like signs become a positive sign | 3+(+2) = 3 + 2 = 5 |
| −(−) | 6−(−3) = 6 + 3 = 9 | |
| +(−) | Two unlike signs become a negative sign | 7+(−2) = 7 − 2 = 5 |
| −(+) | 8−(+2) = 8 − 2 = 6 |
What is the product of 2 negative integers?
RULE 3: The product of two negative integers is positive.
How do two negatives cancel each other out?
The negatives cancel out
When you multiply two negative numbers together, though, the first one flips the sign from positive to negative, and the second one flips it back. In other words, negative numbers cancel each other out: when you multiply a negative number by a negative number, you get a positive number.
What is the sum of two negative integers?

How do you read a negative number?
To help my students understand better, I tell them to think of negative numbers this way:
- The negative sign tells you how far away the number is from the zero.
- So -3 means you are 3 steps away from 0 and -5 means you are 5 steps away from zero.
- Therefore, -5 is smaller than -3 because you are further away from zero.
What’s a negative divided by a negative?
Rule 3: a negative number divided by a negative number equals a positive number. Two negatives make a positive, so a negative number divided by a negative number equals a positive number. For example, -8 / -2 = 4.

Correct answer:
The sum of two negative numbers is always negative, hence, this is the right choice.
How do you find the sum of a negative number?
