The fx-82EX (ClassWiz) is one of the most used calculators in Kenya for high school and university because:
Natural textbook display → shows fractions, roots, logs exactly like in books
274 functions → covers almost all secondary + early university math
Very fast calculations compared to older models
Non-programmable → allowed in most exams (KCSE, university tests)
Has statistics + table functions (important for calculus & data work)
