What Is 3/4 Equal To

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

Solving Equations

Commencement go to the Algebra Computer chief page. In the Calculator's text box, you can enter a math trouble that y'all desire to calculate.

For example, try entering the equation 3x+2=xiv into the text box.

Later y'all enter the expression, Algebra Calculator will print a step-past-stride explanation of how to solve 3x+2=14.

Examples

To see more than examples of problems that Algebra Computer understands, visit the Examples page. Feel free to try them at present.

Math Symbols

If you lot would similar to create your own math expressions, here are some symbols that Algebra Calculator understands:

+ (Improver)
- (Subtraction)
* (Multiplication)
/ (Division)
^ (Exponent: "raised to the power")

Graphing

To graph an equation, enter an equation that starts with "y=" or "x=". Here are some examples: y=2x^2+i, y=3x-1, 10=5, x=y^two.

To graph a point, enter an ordered pair with the x-coordinate and y-coordinate separated by a comma, east.yard., (3,4).

To graph two objects, simply place a semicolon between the two commands, e.g., y=2x^ii+1; y=3x-1.

Polynomials

Algebra Calculator can simplify polynomials, simply information technology only supports polynomials containing the variable ten.

Hither are some examples: 10^2 + x + ii + (2x^ii - 2x), (x+3)^2.

Evaluating Expressions

Algebra Calculator tin can evaluate expressions that contain the variable x.

To evaluate an expression containing x, enter the expression you desire to evaluate, followed by the @ sign and the value you lot want to plug in for x. For example the control 2x @ three evaluates the expression 2x for 10=3, which is equal to ii*iii or 6.

Algebra Calculator tin also evaluate expressions that contain variables x and y. To evaluate an expression containing x and y, enter the expression you lot want to evaluate, followed by the @ sign and an ordered pair containing your 10-value and y-value. Hither is an example evaluating the expression xy at the point (3,4): xy @ (3,4).

Checking Answers For Solving Equations

Just as Algebra Calculator can exist used to evaluate expressions, Algebra Calculator can likewise be used to bank check answers for solving equations containing x.

As an case, suppose we solved 2x+3=7 and got x=two. If we want to plug ii dorsum into the original equation to check our piece of work, we tin can do then: 2x+3=7 @ ii. Since the reply is correct, Algebra Figurer shows a green equals sign.

If we instead effort a value that doesn't work, say x=3 (endeavour 2x+3=7 @ 3), Algebra Figurer shows a red "not equals" sign instead.

To check an answer to a arrangement of equations containing x and y, enter the ii equations separated by a semicolon, followed past the @ sign and an ordered pair containing your x-value and y-value. Example: x+y=vii; x+2y=11 @ (3,four).
