Trig, logs, powers, memory functions, and full keyboard support.
A full scientific calculator covering the functions a basic calculator leaves out: trigonometry (sin, cos, tan and their inverses), logarithms (natural and base-10), powers and roots, and memory functions (M+, M-, MR, MC) for multi-step calculations. It supports both mouse/touch input via on-screen buttons and direct keyboard typing, so it works equally well for quick lookups or longer calculation sessions.
Tap the number and operator buttons to build an expression, or type directly using your keyboard. Use the DEG/RAD toggle to control how sin, cos, and tan interpret angles, then press = to evaluate.
Beyond basic arithmetic, the keypad includes sine, cosine and tangent, square root, base-10 logarithm (log), natural logarithm (ln), the constants π and e, powers with the ^ key, percentages, brackets and four memory keys (MC, MR, M+ and M−). Because it evaluates a full expression, you can type something like (3 + 4) × 2 ^ 3 and press = once, rather than working step by step.
Trigonometric functions depend on the angle mode. In DEG mode sin(30) gives 0.5; in RAD mode the same input is treated as 30 radians and gives a very different value. Switch to RAD when working from formulas that use π, such as sin(π ÷ 6), which also equals 0.5. The calculator follows standard order of operations, so 2 + 3 × 4 gives 14, not 20. Use brackets whenever you want a different order.
You can type on your keyboard: digits, operators, brackets, Enter to calculate, Backspace to delete and Escape to clear. Remember that log means base 10 here while ln is the natural logarithm. For unit changes use the Unit Converter, and for percentage problems the Percentage Calculator is simpler.
Does this support keyboard input?
Yes — digits, + − * /, parentheses, Enter (=), Backspace, and Escape (clear) all work from your keyboard.
Degrees or radians?
Use the DEG/RAD toggle above the display — it defaults to degrees.
