>>Welcome to adding

integers using algebra tiles. Using algebra tiles

is a nice way to get an intuitive feel

for adding integers. When using algebra tiles

we’ll view a blue square as a positive 1, and a red

square as a negative 1. So we need to be

able to understand that if we group a positive

1 and a negative 1 together, the result would be 0. Once we’re ok with

this idea we’ll be able to add integers using

algebra tiles. Let’s try some. Let’s start with one that

we already know how to do, 2 plus 6, we know is equal to 8. But if we wanted to model

this using algebra tiles, this would be the

model for positive 6, and so the sum would be a

total of 8 positive 1s or 8. Now if we want to

consider 5 plus negative 7, positive 5 would consist

of 5 blue squares, and negative 7 would

consist of 7 red squares. And again, the idea here

is that if we combine 1 red and 1 blue square the

result would be 0. So these 2 would be 0, these 2

would be 0, these 2 would be 0, these 2 would be 0,

and these 2 would be 0. So the end result

is 2 red squares, which means our sum

would be negative 2. Notice since negative 7

results in more red squares, the end result is negative. Here we have negative 2 plus 4, 2 red squares would

be negative 2, 4 blue squares would

be positive 4. So if we combine these,

or sum them, this red and this blue would be 0, this

red and this blue would be 0, and the result would

be 2 blue squares, which would be positive 2. Negative 2 plus 4 is

equal to positive 2. Let’s go ahead and try one more. Here we have negative

3 plus negative 4. Here we have 3 red

squares for negative 3, here we have 4 red squares for

negative 4, if we combine these, notice we have a total

of 7 red squares, which is the model

for negative 7. Negative 3 plus negative

4 is equal to negative 7. That will do it for this video, I hope you found these

illustrations helpful.

hhhmm… i can understand little SHHHH >:)

Thank You!
