When writing out a formula use the "carrot" button (^) for exponents with
parenthesis surrounding the base and exponent. For example U=(X^2)
(Y^3). When writing out the formula, only use capital letters to represent a
variable-eg use X, Y, and Z.
For all short answer questions, please bold your answers at the top. Label
which part of the answer your work represents.
Example of a short answer question: Assume X+Y=4.
a) If X=2, what is the value of Y?
b) If instead, X=3, what is the value of Y?
__________________________________________________
a) Y=2
b) Y=1
a) 2+Y=4 => Y=4-2 =>Y=2
b) 3+Y=4 => Y=4-3 => Y=1
