# 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.
