This is a tutorial on how to use the Algebra Calculator, a step-by-step calculator for algebra.

Solving Equations

First go to lớn the Algebra Calculator main page. In the Calculator"s text box, you can enter a math problem that you want lớn calculate. For example, try entering the equation 3x+2=14 into the text box. After you enter the expression, Algebra Calculator will print a step-by-step explanation of how to lớn solve 3x+2=14.

Math Symbols

If you would lượt thích to create your own math expressions, here are some symbols that Algebra Calculator understands: + (Addition)- (Subtraction)* (Multiplication)/ (Division)^ (Exponent: "raised to lớn the power")


To graph an equation, enter an equation that starts with "y=" or "x=". Here are some examples:y=2x^2+1,y=3x-1,x=5,x=y^2. To graph a point, enter an ordered pair with the x-coordinate and y-coordinate separated by a comma, e.g., (3,4). To lớn graph two objects, simply place a semicolon between the two commands, e.g., y=2x^2+1; y=3x-1.


Algebra Calculator can simplify polynomials, but it only supports polynomials containing the variable x. Here are some examples:x^2 + x + 2 + (2x^2 - 2x),(x+3)^2.

Evaluating Expressions

Algebra Calculator can evaluate expressions that contain the variable x. To lớn evaluate an expression containing x, enter the expression you want to lớn evaluate, followed by the

3 evaluates the expression 2x for x=3, which is equal lớn 2*3 or 6. Algebra Calculator can also evaluate expressions that contain variables x & y. To lớn evaluate an expression containing x and y, enter the expression you want to lớn evaluate, followed by the
sign & an ordered pair containing your x-value and y-value. Here is an example evaluating the expression xy at the point (3,4): xy

Checking Answers For Solving Equations

Just as Algebra Calculator can be used to evaluate expressions,Algebra Calculator can also be used to check answers for solving equations containing x. As an example, suppose we solved 2x+3=7 và got x=2. If we want lớn plug 2 back into the original equation to kiểm tra our work, we can bởi so: 2x+3=7
2. Since the answer is right, Algebra Calculator shows a green equals sign. If we instead try a value that doesn"t work, say x=3 (try 2x+3=7
3), Algebra Calculator shows a red "not equals" sign instead. To check an answer lớn a system of equations containing x & y, enter the two equations separated by a semicolon, followed by the
