- Four basic operations: addition(+), subtraction(-), multiplication (*), division (/).
- Changing the sign of a number (+/-)
- Clear enter / clear
- All clear (AC)
- Operation result display (=)
The advanced version of the calculator, in addition to the basic ones, should also implement more advanced operations, including the mandatory:
- Trigonometric functions: sine (sin) cosine (cos) tangent (tan)
- Logarithmic functions: natural logarithm (ln) logarithm (log)
- Calculation of percentages (%)
- Root (sqrt)
- Exponentiation (x ^ 2) (x ^ y)
