When you enter an equation into the calculator, the calculator will begin by expanding (simplifying) the problem. Then it will attempt to solve the equation by using one or more of the following: addition, subtraction, division, taking the square root of each side, factoring, and completing the square.
Variables
Note, If you are unable to select the same paper size as your finished book size in your software, you can use the chart below to scale down an 8.5 x 11 piece of paper to the size of book you want to print. Set your document size to 8.5 x 11 inches, and then apply the appropriate margin settings from the table below.
- Given f (x) = 3x 2 – x + 4, find the simplified form of the following expression, and evaluate at h = 0: This isn't really a functions-operations question, but something like this often arises in the functions-operations context.

Any lowercase letter may be used as a variable.
Exponents
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. Audio hijack 3 6 45. Exponents may not currently 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. Prizmo pro scanning & ocr 3 1.
Multiplication, Addition, and Subtraction

For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessary 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 currently supported; attempts to use the / symbol will result in an error.
Division, Square Root, Radicals, Fractions
The above features are not supported.

x=6How to Check Your Answer with Algebra Calculator
First go to the Algebra Calculator main page.
Type the following:
- First type the equation 2x+3=15.
- Then type the @ symbol.
- Then type x=6.
Clickable Demo
Try entering 2x+3=15 @ x=6 into the text box.After you enter the expression, Algebra Calculator will plug x=6 in for the equation 2x+3=15: 2(6)+3 = 15.
The calculator prints 'True' to let you know that the answer is right.
