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.

Saansouk's Scribe Post

I will be doing a scribe on the first lession we did.

(-6) + (+9) =

Breaking this question down in to words it would have said.

Owe 6 and Have 9 =

The reason this is what it is, it's because the - means that it's Owe and the + means that it's Have.

The job of the brackets these ( and ) are to seperate the numbers.

Finally the + in the middle stands for and it separates the number to tell you that they are what need to be added.

Saansouk's Pay it Forward

Part 1:
Pay it forward is when you help 3 people without asking or taking a reward for and then letting them help someone.

Part 2:
For my pay it forward i worked at a daycare called Busy Bee Daycare. I chose a Daycare because i wanted to show and help little kids you can help without being older. i tried to do some of the cleaning there such as taking out the trash and cleaning the carpets.

Part 3:

Overall it was pretty easy for me to clean and play with the kids, it was a fun experience for me. i got treated like a normal working.
