The time is usually based on a 12-hour clock. A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute. The minute hand rotates through 360° in 60 minutes or 6° per minute. [1]

Time-keeping on this clock uses arithmetic modulo 12. Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics , modular arithmetic is a system of arithmetic for integers , where numbers "wrap around" when reaching a certain value, called the modulus .
TI's long-running TI-30 series being one of the most widely used scientific calculators in classrooms. Casio, Canon, and Sharp, produced their graphing calculators, with Casio's FX series (beginning with the Casio FX-1 in 1972 [9]). Casio was the first company to produce a Graphing calculator (Casio fx-7000G).
The test consists of 80 questions at the elementary and junior high levels (the number is not specified for the high school level but usually consists of 70 questions), which the student must complete in only 30 minutes. Judges give no intermediate time signal—at the end of 30 minutes, students must immediately stop calculator processing, but ...
