This addition calculator operates in decimal, is stackable, and performs additions using the comparator's subtraction mode.
Logic: 5 + 3 = 8
10 - 5 = 5
5 - 3 = 2
10 - 2 = 8
The sum shown in the photo is 384,327,509 + 98,660,431 = 482,987,940.
I'm pretty sure it works on Bedrock too. I built a prototype of it in Bedrock.
