i made this in one evening because i was bored, click the button a few times maybe 10, maybe 100. idk try something

I just make these kind of things to challenge myself Press F9 if something doesn't quitte work to see if errors occured Square root is currently disabled What can this calculator do? - Add and substract - Multiply and divide - Calculate square root and power - Remove characters with the Clear button (C) - Add numbers with keyboard What does it check? - If you try to start with a 'special' character - When solving, check if the expression ends with a 'special' character - If two 'special' are placed after each other - If a number containing a dot (.) is a valid number What can be improved? - The way the + button works, part of a grid right now - Key values count as numbers... noice
