# Basic Operations

You've made
it past addition and subtraction. Guess what's next? It's time to learn the ropes of **multiplying** and **dividing positives **and** negatives**.

The rules for multiplication and division are exactly the same: multiply and divide the numbers as normal. If the signs are the same the answer is positive. If the signs are different, the answer is negative.

Positive | (x) or (÷) | positive | = | positive |

Positive | (x) or (÷) | negative | = | negative |

Negative | (x) or (÷) | positive | = | negative |

Negative | (x) or (÷) | negative | = | positive |

Yep, two wrongs (negatives) actually do make a right (positive).

## Walk this Way

Here is one way to visualize this: if you take a video of someone walking backward (a negative), then play the video in reverse (another negative), the person will be walking forward (in the positive direction).

## Batman and the Joker

Think of someone you consider to be a good guy (like Batman) and someone who is a bad guy (like the Joker). Next, ask these questions:

- If something good (+) happens to someone good (+): is that good or bad, like Batman winning the lottery?
- Good (+)

- If something good (+) happens to someone bad (-): is that good or bad, like the Joker winning the lottery?
- Bad (-)

- If something bad (-) happens to someone good (+): is that good or bad, like Batman being captured?
- Bad (-)

- If something bad (-) happens to someone bad (-): is that good or bad, like the Joker being captured?
- Good (+)
