I’m curious about this but the free strategies are the least interesting. And so I dropped off there. If you’re making money off the practice problems, why even gate the strategies? Just a thought. Love the site design though!

  Thanks! I'm not making money off the practice problems though. In fact, the practice app (https://mentalmathpro.com/mental-math-practice https://mentalmathpro.com/mental-math-practice) is free. I think of it more as a short book (it's priced like one) but has the added benefit that you can practice each lesson as many times as you need. That's why the strategies are gated, they're the most important part. But you do have a point that the first three are the least interesting... Maybe I should offer the first lesson in each category first, or something like that.

  Thank you! If there's anything I can do to improve the site please let me know :) For example, I'm thinking about adding something like a leaderboard, but am not sure if it'll add clutter.

A while back, I made something similar to this site's 'practice app', but bare bones: https://math.twilam.com/ https://math.twilam.com/ Just practice. No strategies. No config options. You just answer a set number of problems and you're done for the day. At the end of each session, you're told how long your daily streak is. No streak freezes. No login. My target audience is my 7yo son.

Shameless plug if you want to practice your hexidecimal math https://matt-savvy.github.io/hex_math/ https://matt-savvy.github.io/hex_math/

You can look into any competition math site and get higher quality problems for free.. academicsarecool.com/#/samples

  That looks like a completely different thing. The article seems to be about learning mental arithmetic tricks like (50+x)^2=(25+x)*100+x^2. https://apkpure.net/zero-hero-math-calculation-pro/com.ankitkumar.maths_tricks_alpha https://apkpure.net/zero-hero-math-calculation-pro/com.ankit... for Android has a lot more tricks to learn and practice for free, but it seems to have been removed from the Play Store during the latest developer agreement update purge.
