What Is 2 X 2
This is a tutorial on how to use the Algebra Reckoner, a step-by-step calculator for algebra.
Solving Equations
Beginning go to the Algebra Calculator master page. In the Computer'south text box, you can enter a math trouble that you want to summate.
For case, endeavour entering the equation 3x+two=14 into the text box.
After you enter the expression, Algebra Calculator volition impress a stride-by-footstep explanation of how to solve 3x+2=14.
Examples
To see more examples of problems that Algebra Calculator understands, visit the Examples page. Feel free to try them now.
Math Symbols
If you would like to create your own math expressions, here are some symbols that Algebra Reckoner understands:
+ (Addition)
- (Subtraction)
* (Multiplication)
/ (Sectionalization)
^ (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-ane, ten=5, x=y^2.
To graph a signal, enter an ordered pair with the x-coordinate and y-coordinate separated by a comma, e.m., (iii,4).
To graph two objects, simply identify a semicolon between the two commands, east.m., y=2x^2+1; y=3x-one.
Polynomials
Algebra Reckoner tin can simplify polynomials, but it but supports polynomials containing the variable x.
Here are some examples: x^two + x + 2 + (2x^two - 2x), (x+3)^2.
Evaluating Expressions
Algebra Computer can evaluate expressions that comprise the variable 10.
To evaluate an expression containing x, enter the expression you desire to evaluate, followed by the @ sign and the value y'all want to plug in for x. For example the command 2x @ 3 evaluates the expression 2x for x=three, which is equal to ii*3 or half dozen.
Algebra Calculator can also evaluate expressions that contain variables x and y. To evaluate an expression containing x and y, enter the expression you desire to evaluate, followed by the @ sign and an ordered pair containing your x-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
But every bit Algebra Reckoner tin can be used to evaluate expressions, Algebra Estimator can also be used to cheque answers for solving equations containing x.
As an example, suppose we solved 2x+three=vii and got x=2. If nosotros want to plug 2 back into the original equation to check our work, we tin can practice so: 2x+3=seven @ 2. Since the reply is correct, Algebra Calculator shows a light-green equals sign.
If nosotros instead try a value that doesn't work, say x=3 (attempt 2x+three=7 @ iii), Algebra Calculator shows a red "not equals" sign instead.
To cheque an answer to a system of equations containing x and y, enter the 2 equations separated past a semicolon, followed by the @ sign and an ordered pair containing your x-value and y-value. Example: x+y=7; ten+2y=11 @ (3,4).
Tablet Way
If you are using a tablet such as the iPad, enter Tablet Mode to brandish a touch on keypad.
