# Rules for Math Bowl Answers

$$An answer that does not follow these rules, even if mathematically correct, will be declared incorrect by the judge.

**1.**Answers that are not integers may not be expressed in decimal form. Fractions must be expressed in reduced form:- (
^{5}⁄_{3}or 1^{2}⁄_{3}) are acceptable,

but (^{10}⁄_{6}, 1.6666 or "1.6 repeating" ) are not acceptable. **2.**All roots must be in reduced form:- $2\sqrt{2}is\; acceptable,\; but\sqrt{8}is\; not\; acceptable.$
**3.**Denominators MUST be "rationalized":- $\frac{2}{\sqrt{2}}is\; acceptable,\; but\sqrt{8}is\; not\; acceptable.$
**4.**Probabilities should be stated in reduced form and not as percentages:- ( $\frac{1}{5}$ or 1:5 ) are acceptable, but ( 3:15 or 20% ) are not acceptable.
**5.**Complex expressions such as*x*^{(y+z)}must be expressed in an unambiguous way.- For example, one could say the following two ways:

"*x*to the parentheses*y*+*z*closed parentheses"

or

"*x*to the quantity*y*+*z*"

but not as follows:

"*x*to the*y*plus*z*," which would be interpreted as*x*+^{y}*z*.
