# Acceptable Forms of Answers

All written answers must meet the following specifications unless instructions state otherwise.

- Answers must be clearly written in the answer blank provided.
- All fractions must be completely simplified in proper, improper or mixed form. The numerator and denominator must be integers that share no nontrivial common factors.
- Decimal approximations are not acceptable unless specifically requested.
- All radicals must be completely “simplified”, including no perfect square factors under the radicand and no radicals in the denominator.
- Answers must be in generally accepted mathematical form. If an answer is ambiguous, it will be marked wrong.
- Answers like (±3,±4) are ambiguous and are always wrong, regardless of what the correct answer is.
- Proper set notation, proper interval notation, or careful use of the words “or” or “and” must be used when dealing with inequalities.
- Any answer expressed with a fractional exponent must be in simple form, as if it were rewritten in radical form. For example 2^(7/5) must be written as 2*2^(2/5).
- An ordered pair must be given in standard notation with parentheses. Omitting the parentheses makes the answer incorrect.

## Exceptions

The question writer may always include specific instructions regarding the form of an answer, overriding the generic league rules.
