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

Solving Equations

First go khổng lồ the Algebra Calculator main page. In the Calculator"s text box, you can enter a math problem that you want to 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.


To see more examples of problems that Algebra Calculator understands, visit the Examples page. Feel không tính phí to try them now.

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 khổng lồ 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. Lớn 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 evaluate, followed by the

3 evaluates the expression 2x for x=3, which is equal to lớn 2*3 or 6. Algebra Calculator can also evaluate expressions that contain variables x và y. Lớn evaluate an expression containing x & y, enter the expression you want lớn evaluate, followed by the
sign và an ordered pair containing your x-value và 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 khổng lồ 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 do 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 to a system of equations containing x và y, enter the two equations separated by a semicolon, followed by the
