Frequently asked questions
What functions does the scientific calculator support?
Basic: +, −, ×, ÷. Advanced: sin, cos, tan (radians), log (base 10), ln (natural log), √ (square root), x² (square), x^y (power), π (pi), e (Euler), ! (factorial), parentheses for grouping.
How to use trigonometric functions?

What's the order of operations?
Standard PEMDAS: Parentheses first, then Exponents, Multiplication & Division (left to right), Addition & Subtraction (left to right). The calculator follows this automatically.
Does it work for school exams?
For learning and homework yes. For Pakistani board exams (matric/intermediate), only specific approved physical calculators are allowed. Check your board's policy.
Can it handle complex numbers?
