Calculator Applications is one of several academic events sanctioned by the University Interscholastic League (UIL) in Texas, US.
It is also a competition held by the Texas Math and Science Coaches Association, using the same rules as the UIL.
Calculator Applications replaced the Slide Rule contest previously held by UIL.
Calculators must: For a question to score as correct, the student must answer it to the third significant digit—with allowable error in the third digit of plus or minus one, except for integer, dollar sign, and certain stated problems that require least significant digits.
Scoring for these problems, for tiebreaker purposes, is the same as for overall except no points are deducted for incorrect answers.
[1] NOTE: UIL did not recognize a team championship in this event until the 1988-89 scholastic year.
