Calculator Pipeline Simulator

Interactive calculators — from a basic four-function pad to a running average on a live dashboard — all share the same core: fold one new value at a time into an accumulator using a fixed update rule. This simulator makes that fold visible as a physical conveyor. Numbered blocks spawn at a steady rate, travel down the lane and drop into an operator node, which combines each one into the running result according to the selected operation — sum, product, max, or running average. Watch how the choice of operation changes the accumulator's behavior: sums climb steadily, products explode or stall depending on whether zero shows up, max only ever increases, and the running average settles as more samples arrive.
