Calculations / Graph Function

Basic calculation functions:

Negative numbers; exponents; parenthetical addition, subtraction, multiplication, di-

vision (with priority sequence judgement function - true algebraic logic)

Built-in scientific functions:

Trigonometric/inverse trigonometric functions (angle units: degrees, radians, grads);

logarithmic/exponential functions; reciprocals, factorials; square roots; cube roots;

powers; roots; squares; negative signing; exponential notation input; , parenthetical

calculations; internal rounding; random numbers; angle unit specification; fractions;

decimal-sexagesimal conversion; coordinate transformation; permutation; combina-

tion; number of decimal place and significant digit specification

Built-in functions:

Exponential notation range; delete, insert, answer functions; replay; memory status
