# 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.

### Functions

sqrt Square Root of a value or expression. sine of a value or expression cosine of a value or expression tangent of a value or expression inverse sine (arcsine) of a value or expression inverse cosine (arccos) of a value or expression inverse tangent (arctangent) of a value or expression Hyperbolic sine of a value or expression Hyperbolic cosine of a value or expression Hyperbolic tangent of a value or expression e (the Euler Constant) raised to the power of a value or expression The natural logarithm of a value or expression The base-10 logarithm of a value or expression Returns the largest (closest to positive infinity) value that is not greater than the argument and is equal to a mathematical integer. Returns the smallest (closest to negative infinity) value that is not less than the argument and is equal to a mathematical integer. Absolute value (distance from zero) of a value or expression Sign (+1 or -1) of a value or expression

### Constants

pi The constant π (3.141592654...) The Euler constant (2.71828...), the base for the natural logarithm
