Standard Calculator

Sometimes you just need to add, subtract, multiply, or divide. Phone calculators work, but they're buried in apps. A quick web calculator is always a tab away. This basic calculator handles addition, subtraction, multiplication, division, percentage, square root, and memory. It runs entirely in your browser—no server calls, no signup. Click or type, get the result. Works offline once loaded.

Use it for quick math: tip calculations, unit price comparisons, splitting a bill, or checking totals. The memory buttons (M+, M-, MR) let you accumulate values—handy when adding a series of numbers. Percentage works in the standard way: enter a number, press %, and you get that percentage of the previous value. Square root is one click. The interface is minimal on purpose: no bloat, just the operations most people need.

Developers and students use it for quick sanity checks. "Is 17 * 23 really 391?" or "What's the square root of 144?"—verify without opening a heavy app. The calculator doesn't track or store your input. Everything stays in your browser session. Close the tab and it's gone. No accounts, no analytics on your calculations. Just math when you need it.

It won't replace a scientific calculator or a spreadsheet. For trigonometry, logarithms, or complex expressions, use a dedicated tool. For everyday arithmetic, this is enough. Bookmark it for those moments when you need a quick result—budgeting, shopping, or a random calculation—without digging through your phone or desktop.
