[Solved]How do I Addition and Subtraction textbox value?

i have 2 easy question

1.How I can plus “textbox1” value and “textbox2” value to result in “textbox3” when click “ok1” button.

2.How I can Subtract “textbox_1” value and “textbox_2” value to result in “textbox_3” click “ok2” button.

anybody can help me.

*Sorry to my bad english translator

Set texbox3 text to str(int(textbox1.text)+int(textbox2.text))

If you need decimal points, use float() instead of int()
