Hello there, hunters! I'm V, and we are delighted to introduce our app, Math99th. Math99th was created to address a significant issue in the current state of education. Our founder believes that education should be affordable and tailored to each student, regardless of their background. Our app is straightforward, featuring two modes: Adaptive Learning and Electric Training. Let's begin with Adaptive Learning, where you can take as much time as needed to solve each problem. After each question, our system will rate you based on an Elo rating system. Successfully tackling more challenging questions earns you more points, but be cautious—if an easy question is answered incorrectly, you may lose a substantial amount of points for a single question. Not to worry, though; we offer an almost unlimited supply of questions, and our app requires no payment, allowing you an unlimited number of tries. We believe we are among the first to achieve this. We eagerly await your feedback and invite you to join us in ushering in a new era of learning.
