Hey if you're still here i can't getmy equal button to work can you make a video about just the equal button?

@ObsidianSoftEducation 10 месяцев назад

Kindly look at the written tutorial for better understanding: obsidiansofteducation.blogspot.com/p/calculator-in-mit-app-inventor.html The aia project file is also given in this tutorial.

@jakubhribal4590 Месяц назад

Hi, I followed your tutorial and programmed a calculator, but when I click on an operator first and then a number and equals, it shows an error. Could you help me modify it so that, except for the minus sign, an operator cannot be entered first? Thank you.

@ObsidianSoftEducation Месяц назад

In our equal button click event, in the very beginning, we check that our second number is not empty by comparing the second number with an empty text block. Similarly, you will have to add a check in your operator button click events that the first number is not empty.

@user-ng8sw3nl4y Год назад

i tried this and my decimal is not working, what should i do?

@ObsidianSoftEducation Год назад

Can you please explain the problem further? Do you mean that the decimal point is not showing when you press the button or decimal operations are not being performed?

@aminjan80 Год назад

Hi There Thanks alot for the demo, i have an issue with the equal sign it is not working

@ObsidianSoftEducation Год назад

Hello. What is the error?

@aminjan80 Год назад

@@ObsidianSoftEducation Hi Thanks for the reply Everything is fine but the equal sign doesn’t bring the value after the calculation if add 2+3 and then press the equal sign I can’t get the answer.

@ObsidianSoftEducation Год назад

@@aminjan80 are you able to see 2+3 written on the screen? if yes, then the problem could be inside the equal button click event. Have a look at it again. If you are still unable to solve it, send me a screenshot of equal button click event at obsidiansoftc@gmail.com

@aminjan80 Год назад

@@ObsidianSoftEducation Hi dear. yeah now it works perfectly and i have learnt alot from it thank you so much

The second number doesn't display on the screen, it's just the first number and the output

@ObsidianSoftEducation 8 месяцев назад

First of all, check whether you have given a different color to second number. The default color is black so if background is also black, you will not be able to see the second number. Secondly, check the code for missing code. A number is considered a second number if the user has pressed any of the operator buttons. Please check whether you are setting the operator variable whenever an operator button such as +,-,/ or x is pressed. Also, all number keys should check for operator variable in an if else condition. This is how we differentiate between first and second number. I have shared the aia file too. You can import it too and compare with your code.

@Sxeci 8 месяцев назад

I can't unzip the aia file

@ObsidianSoftEducation 8 месяцев назад

@SternritterA you don’t unzip it. You import it in mit app inventor. Please follow steps mentioned here: obsidiansofteducation.blogspot.com/p/mit-app-inventor-projects.html

@Sxeci 8 месяцев назад

Thanks it works just fine.

@ObsidianSoftEducation 8 месяцев назад

Glad to hear that it works now.

Hello. Are you having a problem with the decimal button code? This is to avoid the entry of numbers like 5.89.2 (more than one decimal point in a number)
