2+2 Calculator

Plain and scientific calculator inside the chat window

Listed in ChatGPT

Overview

What 2+2 Calculator does

2+2 Calculator from Spheric Admin Ltd puts a calculator interface into ChatGPT for the four basic arithmetic operations.

Two modes are listed. Plain mode handles everyday sums, while scientific mode adds powers, roots, exponentials, logarithms, and trigonometric functions, with a switch between degrees and radians for angle input. The short description also flags percentages and fractions.

The record calls the app simple and says nothing about graphing, unit conversion, equation solving, or keeping a history of past calculations, so the entry is best read as covering a calculator widget and little more.

Who it is for

Someone who wants arithmetic and trigonometry handled by a calculator interface in the chat rather than by prose.

What stands out

It covers the scientific function set, including logarithms and a degrees or radians switch, in a small utility app.

Where 2+2 Calculator is listed

2+2 Calculator is listed in the ChatGPT apps directory only. Spheric Admin Ltd has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
