## What are the rules for negative numbers?

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 |

**Can negative numbers be arithmetic?**

The laws of arithmetic for negative numbers ensure that the common-sense idea of an opposite is reflected in arithmetic. For example, −(−3) = 3 because the opposite of an opposite is the original value. Every real number other than zero is either positive or negative.

**Why do 2 negatives multiplied make a positive?**

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.

### What does a negative times a negative make?

Why a negative times a negative is a positive.

**Is 0 a negative number?**

The number zero is neither positive nor negative. Positive and negative numbers are sometimes called signed numbers.

**Why does minus negative equal positive?**

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.

#### How does the positive and negative numbers game work?

This competitive card game will help your child get comfortable learning the difference between the value of positive and negative numbers using a deck of cards. Players work together to negotiate the value of playing cards by figuring out who has the highest positive card value. Thank you for your input.

**How to tell the difference between positive and negative numbers?**

Let the players know that red cards are negative numbers and black cards are positive numbers. Have them all turn over the top card on their stacks at the same time. Ask them who has the highest number. The player with the highest number should take all four cards and place them at the bottom of his stack.

**Are there any rational numbers that are negative?**

They can be fractions, decimals, rational and irrational numbers. -13, -½ , -√2, -6.4 and -123 are all negative numbers. We have a page dedicated to learning about negative numbers below.
