ⓘ About this tool 🔄 Last updated 1 Sep 2026 ✓ Reviewed by TopToolAI Team

A simple, no-frills calculator for everyday addition, subtraction, multiplication and division — right there in your browser when you don't want to dig out your phone. 47 x 3 gives 141, and (250 + 75) divided by 5 gives 65 — handled the way a physical calculator would, without needing to open a separate app.

How to use Basic Calculator

A short guide to using this tool. Open it if you need help.

  1. 1

    Use the number buttons to type your first number. The display on top shows what you have typed so far.

  2. 2

    Tap an operator: + to add, - to subtract, * to multiply or / to divide. Then type the second number. You can keep chaining, for example 12 + 8 * 3.

  3. 3

    Tap = to see the answer. Note that multiplication and division are worked out before addition and subtraction, like on a school calculator.

  4. 4

    Made a mistake? Tap Clear to wipe the display and start again from 0.

Basic Calculator FAQs

Does it handle decimals?
Yes, it works fine with decimal numbers for both input and results.
Can I use it for percentages?
For dedicated percentage work the Percentage Calculator is a better fit — this one focuses on the four basic operations.
Does it follow order of operations (BODMAS/PEMDAS)?
It performs one operation between two numbers at a time rather than parsing a full expression — for multi-step math, calculate step by step in the order you need.
Can I use negative numbers?
Yes, both fields accept negative numbers for calculations like subtraction below zero.
