CLUSTER ARITHMETIC-CALCULATIONS-WEB · 13 ENTRIES · EARLIEST ENTRY unknown

Basic arithmetic web calculators

This cluster consists of web applications and tools that perform basic arithmetic operations, often with a simple calculator interface and quick numeric results. A few variations exist, such as rounding to a chosen decimal place or visualizing multi-digit addition with shapes. The cluster's dated history is too thin to read a shape from, with only one dated entry before the index start and many members undated. The traction leader is CALCULATOR with 1 star, followed by simple-calculator-hub and addblocks with 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 13 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
