# Equation Simplifying Calculator

### Quick-Start Guide

Enter an equation in the box, then click “SIMPLIFY”. The calculator will

simplify the equation step-by-step, and display the result. If you wish

to solve the equation, use the

Equation Solving Calculator.

#### Variables

Any lowercase letter may be used as a variable.

#### Exponents

Exponents are supported on variables using the ^ (caret) symbol. For example, to express x^{2}, enter x^2.

Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not be placed

on numbers, brackets, or parentheses.

#### Parentheses and Brackets

Parentheses ( ) and brackets [ ] may be used to group terms as in a standard equation or expression.

#### Multiplication, Addition, and Subtraction

For addition and subtraction, use the standard + and – symbols respectively. For multiplication, use the *

symbol. A * symbol is not necessiary when multiplying a number by a variable. For instance: 2 * x can also

be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).

The * is also optional when multiplying with parentheses, example: (x + 1)(x – 1).

#### Order of Operations

The calculator follows the standard order of operations taught by most algebra books – Parentheses, Exponents,

Multiplication and Division, Addition and Subtraction. The only exception is that division is not supported;

attempts to use the / symbol will result in an error.

#### Division, Square Root, Radicals, Fractions

The above features are not supported.
