Write a simplified algebraic expression for each Expression Mat below.
Remove the zero pairs.
What is an expression for the remaining tiles?
On this mat, both
-tiles in the (+) region can be removed, since they make a zero pair.
Next, flip the
unit tile in the (-) region to the (+) region, and then simplify.
Unlike in parts (a) and (b), this problem has no zero pairs.
However, here is an un-simplified expression to get you started.
Can you simplify that expression?
