What Is a Scientific Calculator?
A scientific calculator is an advanced mathematical tool that performs complex calculations beyond basic arithmetic. It is widely used in mathematics, science, engineering, and statistics. It follows the PEMDAS/BODMAS order so complex expressions are solved correctly, and supports trigonometric, hyperbolic, logarithmic, exponential, and combinatorial functions.
Trigonometric & Inverse Functions
Switch between RAD and DEG with one tap. Tap 2nd to access inverse trig functions.
- sin, cos, tan
- sin⁻¹, cos⁻¹, tan⁻¹ (arcsine, arccosine, arctangent)
- sinh, cosh, tanh and their inverses
Logarithms, Exponentials & Powers
- log: base-10 logarithm; log₂: base-2 (via 2nd)
- ln: natural logarithm; eˣ: exponential (via 2nd)
- logₙ(b, x): logarithm with arbitrary base b
- x², x³, x^y for arbitrary powers
- √, ∛, nthroot(x, n)
- EXP for scientific notation, e.g. 6.022 × 10²³
Combinatorics, Modulo & Absolute Value
- x!: factorial (extended to non-integers via the gamma function)
- nCr, nPr: combinations and permutations
- mod: modulo operator for remainders
- |x|: absolute value
Memory, Ans & History
- MS / MR / MC / M+ / M-: store, recall, clear, add, subtract memory
- Ans: reuses the last answer in a new expression
- Recent calculations appear in the history panel below the keypad
Implicit Multiplication & Smart Parsing
Expressions like 2(3+4), 3π, 2sin(π/6), and (1+2)(3+4) evaluate naturally. Unclosed parentheses are auto-completed when you press equals.
