Hi Jose. So far so good with your calculator project.
I agree with @elaineleung on the theme switcher where using radio buttons should have been used. Radio buttons allow one selection at any given point - which is exactly what we want. Checkboxes do not or are not meant for that purpose.
- have a maximum digit/number that the calculator can take , at present the calculator can take any number as long as one can press the keyboard.
- try the following calculation
0.2 + 0.1
- well done , at most the calculator can accept one decimal point
