Basic & Scientific — two powerful calculators in one place.
A basic calculator handles everyday arithmetic — addition, subtraction, multiplication, division — with the same button layout as a physical calculator, plus memory functions and a history log so you're not retyping numbers you already calculated. It also includes a full scientific mode for trig, logarithms, and other advanced functions when you need them.
Switching between a phone's default calculator app and a browser tab gets annoying when you're doing several calculations back to back, especially while working on something else. This tool exists as a fast, always-available calculator you can pull up in any browser tab without hunting for an app.
It functions exactly like a standard handheld calculator, processing operations in the expected order (multiplication and division before addition and subtraction), with the added convenience of keyboard shortcuts and a scrollable history so you don't lose track of previous results during a longer session of calculations.
Yes, it correctly processes multiplication and division before addition and subtraction, following standard math rules.
Yes, full keyboard input is supported for numbers, operators, and the Enter key to calculate.
M+ adds the current result to memory, M− subtracts from it, MR recalls the stored value, and MC clears the memory entirely.
Yes, switching to Scientific mode unlocks trigonometric functions, logarithms, powers, roots, and constants like π and e.
Yes, your last 20 calculations are stored in the history panel for quick reference during your session.
