The following are guidelines to consider while competing in this year’s contest:
· Mathematical terminology is used throughout all of the tests. You may wish to prepare your younger students for words like “sum”, “product”, “difference”, “quotient”, "integer", "sequence", etc.
· Figures are not necessarily drawn to scale.
· Problems are not necessarily in order of difficulty. Contestants are encouraged to look the entire test over during the time interval. A competitor who focuses on early hard problems may not get to later easy problems.
· The words “mean” and “average”, without qualifiers, shall represent the arithmetic mean.
· In triangles, unless otherwise specified, uppercase letters represent the vertices (or angles) of a triangle, lower case letters represent the lengths of the sides opposite these vertices. E.g. in triangle ABC, a, b, and c are the lengths of the sides opposite A, B, and C.
· “Natural numbers” and “counting numbers” are considered to be the same set, and do not contain zero.
· If consistent units are used throughout a problem, assume the answer should be in terms of those units as well, unless otherwise specified. If no units are used in a problem, assume “units”, “square units”, etc., were used throughout.
should bring a pencil and an eraser to each competition. All other
materials will be provided.
