A mathematical signal strength circuit is a circuit which operates on signal strength, such as arithmetic and comparison.

Basics
Since there is no redstone adder in Minec raft, we need to convert addition into subtraction. a + b = a + b - 15 + 15 = - 15 + a + b + 15 = - (15 - a - b) + 15 = 15 - (15 - a - b)
