Draw a chip model to represent -4 – (-3). This should use a take-away interpretation of subtraction. You will get no credit if appeal to a computational rule and represent this as -4 + 3. (Look back at our notes on subtracting negatives if you need to refresh your memory.) Mark out the chips that are to be removed, and circle what is left. Be sure I can tell which chips are positive and negative.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
