So I'm currently losing sleep over this problem I have and I would be grateful if someone could help me.
The problem itself is simple. I have two variables, let's call them x and y and I want these two variables to make one number: z. so for example let x = 3 and y = 7 I need z to be 37
I know the answer is simple as well but I just can't find the search words for it. Thanks in advance!!
