How would the following problem be represented using colored tiles? -7 + (-3) seven red tiles plus three blue tiles seven red tiles plus three red tiles seven blue tiles plus three red tiles seven blue tiles plus three blue tiles

Ok, we have the equation:

-7 + (-3)

Both numbers are negative, so the solution of this will be:

-7 + (-3) = -7 - 3 = -10.

Now, how we can represent it with tiles?

First we need to define, which tiles are the ones representing negative numbers?

We can use:

Red = positive

Blue = negative.

Then:

-7 is represented with seven blue tiles

-3 is represented with tree blue tiles

then:

(-7) + (-3)

will be represented with seven blue tiles, plus tree blue tiles.

When we add them, we have a total of 10 blue tiles, and as blue tiles represent negative numbers, 10 blue tiles is equal to -10.

-7-3

2 5/8 is the final answer! : )
