![]() If you are using a tablet such as the iPad, enter Tablet Mode to display a touch keypad. To check an answer to a system of equations containing x and y, enter the two equations separated by a semicolon, followed by the sign and an ordered pair containing your x-value and y-value. 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. Since the answer is right, Algebra Calculator shows a green equals sign. The examples will show you different problems. If we want to plug 2 back into the original equation to check our work, we can do so: 2x+3=7 2. Share 29K views 5 years ago Using Symbolab If you are unsure how to enter in a problem into Symbolab, take a look at the examples in each calculator. Design the interface for it Implement the interface Connect the interface to the actual calculation engine. ![]() Just as Algebra Calculator can be used to evaluate expressions,Īlgebra Calculator can also be used to check answers for solving equations containing x.Īs an example, suppose we solved 2x+3=7 and got x=2. Decide what the calculator is supposed to do. Use Coupon Code 67OFFSCHOOL for Extra Discount All. Here is an example evaluating the expression xy at the point (3,4): xy (3,4). Tutorials and Resources for the Casio Classwiz fx-991EX Scientific Calculator. To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the sign and an ordered pair containing your x-value and y-value. To evaluate an expression containing x, enter the expression you want to evaluate, followed by the sign and the value you want to plug in for x.įor example the command 2x 3 evaluates the expression 2x for x=3, which is equal to 2*3 or 6.Īlgebra Calculator can also evaluate expressions that contain variables x and y. To graph two objects, simply place a semicolon between the two commands, e.g.,Īlgebra Calculator can simplify polynomials, but it only supports polynomials containing the variable x.Īlgebra Calculator can evaluate expressions that contain the variable x. To graph a point, enter an ordered pair with the x-coordinate and y-coordinate separated by a comma, e.g., (3,4). To graph an equation, enter an equation that starts with "y=" or "x=". If you would like to create your own math expressions, here are some symbols that Algebra Calculator understands: To see more examples of problems that Algebra Calculator understands, visit theĮxamples page. In the Calculator's text box, you can enter a math problem that you want to calculate.įor example, try entering the equation 3x+2=14 into the text box.Īfter you enter the expression, Algebra Calculator will print a step-by-step explanation of how to solve 3x+2=14. ![]() This is a tutorial on how to use the Algebra Calculator, a step-by-step calculator for algebra.įirst go to the Algebra Calculator main page. ![]()
