Create a calculator in PowerApps

Now, we will see how to create a simple calculator in Power Apps.

First, we will create a canvas app from the PowerApps.com site.

If you are new to PowerApps Canvas App, check out the below URLs:

• Create a canvas app from Excel in Power Apps (Step by Step tutorial)

Here create an app, and you may choose Phone layout or Tablet layout.

Then, add the below controls to your screen: TextBox and Label from Power Apps input controls.

You can change the name of your control to recognize the control easily. Below is my screen, which looks like this after adding TextBox and Label.

Here I have set the background Image as black Image and changed the button color to orange and the Textbox to blue.

Next, click on the first textbox and go to the Onchange property and set the variable as N1. This means whatever value you enter in the textbox, it will store in the N1 variable.

You can visit the Microsoft site to learn more about creating a variable in PowerApps.

The same step you have to follow here, go to the Onchange property of your textbox and Set the value in the N2 variable. This means whatever the value you enter in the textbox, it will store in variable N2.

Next, click on the Plus button and go to the OnSelect property and store the N1 and N2 values in a result variable. So do the same for the other button as well.

+ button -> UpdateContext({result: N1 + N2 });
- button -> UpdateContext({result: N1 - N2 });
* button -> UpdateContext({result: N1 * N2 });
/ button -> UpdateContext({result: N1 / N2 });

Next go to the Output Textbox and set the result in Textbox property Text.

After set everything, Run the apps and see the output as below.

This is a simple Power Apps calculator.
