CPM Homework Help : CC2MN Problem 3-96

Represent each operation below by drawing $-$ tiles. Then simplify each expression.

$-6+(-2)$

Hint (a):

Gavin had a similar problem. He was told to represent $-4+(-1)$ by drawing $-$ pieces. Look at his diagram below. Then use Gavin's method to solve your problem.

$-\ - \ - \ -\\ \quad \quad \quad \nwarrow\\ \quad \quad \quad \ \ \ \enclose{circle}-$

This diagram represents four negative numbers. The arrow pointing to the negative numbers means to combine with them with one more negative number.

$-6-(-2)$
Hint (b):
Gavin was told to represent $-4-(-1)$ by drawing $-$ pieces. Again, look at the diagram below and then use Gavin's method to solve your problem.
$-\ - \ - \quad \ \enclose{circle}- \\ \quad \quad \quad \quad \quad \ \ \searrow$
This diagram represents four negative numbers where one of them was removed.
