Oh, I should mention - the above picture runs in real-time already. I can type in where the 5s are, a different number, and they will automatically add up in real-time. That’s why it shows 10.
It’s just that I don’t have a visualization for the connections/wires/inputs and outputs, yet, so you can’t see them connected together. Because the output of “frame” connects to the first 5 box, the 5 box connects to the second 5 box, so the number gets copied, and then they both feed into +, and then plus outputs into the final box to show you 5+5=10.
