## Description

Math Flash Cards is a child-friendly Chrome extension designed to help kids master essential math skills including addition, subtraction, multiplication, and division. Users can customize top and bottom number ranges—0 to 50 for addition and subtraction, and 0 to 20 for multiplication and division—to tailor difficulty. 

Key features include the ability to combine two math operations, set adjustable countdown timers to simulate test conditions, and choose between ordered or random card sequences to aid faster memorization. The app also supports showing correct answers after mistakes, allowing three attempts per question, and reviewing missed cards at the end for reinforcement. An encouraging friendly voice and a scores list enhance motivation and track progress. Supported by ads, this extension offers a comprehensive and engaging way to improve math skills.
