Order of Operations Calculator

Type in your sum to see how to solve it step by step. Examples: 2+3*4 or 3/4*3

Description

Just type in sums like these (see Order of Operations for more detail):

Examples:

1+2*3
7 + (6 * 5^2 + 3)
cos(1.2^2)+3
(5−3)(5+3)
( −6 + √(6²−4×5×1) ) / (2×5)
sqrt(3^2+4^2)

You will see what the calculator thinks you entered (which may be a little different to what you typed), and then a step-by-step solution.

Note: there can be more than one way to find a solution.

The calculator is still under development and may get things wrong, so be careful!

Tree View

Press the "tree" button to see your sum as a tree. You would do the calculations from the top down ... sometimes you have a choice which calculation to do first.
