What does a negative plus a negative equal?
What does a negative plus a negative equal?
When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out.
Why does a negative and a negative make a positive?
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.
Is a negative times a negative times a negative a positive?
Ideally, the second negative should change the sign of our original number (which is also negative). So, our original negative sign is changed into a positive sign when a negative is multiplied to it. Thus, As multiplying with negative will change the sign, a negative times a negative equal a positive.
What’s a negative plus a positive?
When multiplying (or dividing) two numbers with the same signs, the resulting answer is positive. If one is positive and the other negative, the answer will be negative. e.g. (positive )
Can two negatives make a positive baby?
No, because to be rh negative, one must have TWO rh negative alleles. The rh factor is recessive. If both parents are rh negative, they must have ONLY rh negative alleles. Therefore they do not have any positive alleles to pass on to their children.
What happens if you multiply two negative numbers?
There are two simple rules to remember: When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive.
What does a negative minus a positive equal?
Solutions. Subtracting a negative number from a positive number result in a positive answer. This problem can also be re-written as 6 + 3 = 9. Subtracting a negative number from a positive number results in a positive answer.
How do you add two negatives?
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 does 2 negatives make?
“Two negatives make a positive” is one of those math slogans that drives me crazy, because it is so pithy, so memorable, so easy to apply… while also being so vague and non-mathematical that I’m amazed students find it useful at all.

What are the four 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 correct order of operations?
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
