How to Use the Scientific Calculator
Basic Operations
The calculator works similarly to a physical scientific calculator. Enter your calculation using the buttons or keyboard, then press "=" to see the result. Use parentheses to control the order of operations.
Example Calculations:
3 + 5 × 2 = 13
Multiplication before addition
(3 + 5) × 2 = 16
Parentheses change order
sin(30) = 0.5
Trigonometric function
log(100) = 2
Logarithm base 10
Memory Functions
- M+: Add current result to memory
- M-: Subtract current result from memory
- MR: Recall memory value
- MC: Clear memory (use AC button)
Advanced Functions

Frequently Asked Questions
How do I switch between degrees and radians?
Use the "Deg/Rad" button to toggle between degree and radian modes for trigonometric calculations. The current mode is displayed above the calculator display.
How do I use scientific notation?
Use the "EXP" button to enter numbers in scientific notation. For example, to enter 6.022 × 10²³, press: 6.022 EXP 23.
Can I use keyboard input?
Yes, you can type directly into the calculator. Most standard calculator keys are supported, including numbers, operators (+-*/), and parentheses.
How do I calculate exponents and roots?
Use x^y for exponents (e.g., 2^3 = 8), √ for square roots, 3√ for cube roots, and y√x for nth roots (e.g., 4 y√x 81 calculates the 4th root of 81).
What's the difference between log and ln?
"log" is the logarithm base 10, while "ln" is the natural logarithm (base e). For example, log(100) = 2 and ln(e³) = 3.
