Saansouk's multiplying integer scribe

The Sign rule

• When multiplying integers with the same value (-2) x (-2) = the product will always be positive.
• When the value of integers are different (+2) x (-2) = the product will be negative

The Same Value:
When the first number is a (-) it means that if the the second number was a (-) you would have had to make a zero pairs and then take away the negatives.

Example: (--)(--)--->

         (++)(++)

When the first number is a (+) and the second number is a (+) you are basically doing regular multiplication.

Example: (++)(++)

The Opposite Value:

When the first number is a (+) and the second number is a (-) you are multiplying regular numbers just with a negative with it.

Example: (--)(--)

When the first number is a (-) and the second number is a (+) you are going to make a zero pairs but take away the positives.

Example: (--)(--)

                      (++)(++)--->

Number Lines:

This includes all of the sign rule example all you have to do is put how many arrows the first amount uses and then add to the number line using the second number.

Examples:

                   0

<-----------+------+--->

                   -->-->(+4)

                   0

<---+------+---------->

    (-4) <--<--

That concludes this scribe and I hope it was a good one.
