Hi guys! I was booooored and did that. Just a little timewaster project XD The only thing you need to do is to click that robot and enter any number, and he will say if it is even or odd. After he says that number is even, the even button will become green. And after he says that number is odd, the odd button will become green. There is no point in entering letters, he will say "even" to all of them. So have fun! Also I don't like math but I had to do something soooo
