Simplifying Expressions Calculator
When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. Use the following rules to enter expressions into the calculator.
Any lowercase letter may be used as a variable.
Exponents are supported on variables using the ^ (caret) symbol. For example, to express x2, 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 expression.
Multiplication, Addition, and Subtraction
For addition and subtraction, use the standard + and – symbols respectively. For multiplication, use the * symbol. A * symbol is optional 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 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
Division, square root, radicals, and fractions are not supported.
