everything is now more colorful. its happy.
To Xray and the downloaders, to use calculator blocks,
you need the bank shaped thing and click it, if it's negative then you are using a negative one.
use the positive one unless you are complex.
the signal must hit a calculator block. it must hit the 2 inputs, the splitters do not want that.
color blocks are made for fun.
remove the warning pls.
if there are more than 2 inputs thats fine. put signals on the X>2 inputs
