## Description

Calculator+ is an intuitive calculator extension designed for everyday use, whether shopping, calculating taxes, or estimating work costs. It supports full formula input allowing you to perform collective calculations like "100+30-50" with instant answer display as you type.

Key features include one-touch discount buttons (e.g., 5%, 10%, 15%), VAT calculation with easy tax rate selection, memory keys for subtotal and total calculations, and a rich history log that saves your calculations for reuse and summation. The calculator also saves your formula mid-calculation for seamless resuming. For extra engagement, a mini-game challenges your arithmetic skills during downtime. Choose from several clean designs to fit your preference and enjoy easy corrections with backspace and multifunctional keys like "00".

This extension streamlines and enhances your calculation tasks with convenience and clarity.
