A free, simple online calculator for everyday addition, subtraction, multiplication, division and percentages.
This is a sequential four-function calculator. Enter a number, choose an operation, enter the next number and press =. Operations are evaluated in the order entered rather than using PEMDAS.
Example
For example, 2 + 3 × 4 is evaluated as (2 + 3) × 4 = 20. Use a scientific calculator when you need standard mathematical order of operations.
Why does typing 2 + 3 × 4 give 20 here instead of 14?
This is a simple sequential calculator, just like the physical calculator in your kitchen drawer — it does each operation in the order you press it, left to right, rather than following algebra's "order of operations" (PEMDAS). For strict order-of-operations math, use a scientific calculator instead.
What's the difference between the "C" and "⌫" buttons?
"C" wipes everything and starts a fresh calculation from zero. "⌫" (backspace) just deletes the last digit you typed, so you can fix a typo without losing the whole entry.
