The Scalar Math node. Its title follows the operation you pick.
When to use it
Adds, subtracts, multiplies or divides two numbers. This is how a graph computes a setting from another value instead of hard-coding it: half the source triangle count, twice the measured distance.
Divide by zero is reported as a node error and publishes nothing, rather than emitting an infinity or a silent zero. An infinity travelling into a mesh operation as an edge length or a vertex budget would blow up there, and you would blame the mesh node.
When nothing is published, the consumer falls back to its own setting. That is what a downstream node quietly ignoring its wire looks like.
