What it does
Thirteen Indian-style mental-math methods that turn 99×99 into a five-second exercise. Ranked from Level 1 to Master 7. No ads, fully offline, ¥350 one-time.
From Level 1 to Master 7, each rank teaches a different way to see a multiplication. No ads, no network, just ink-quiet focus. Indian-style mental math is not a shortcut. You split the place values, find a symmetry, and rewrite the expression as something simpler. The long form disappears. Each method is the shortest path through one specific pattern. You don't memorise it — you learn to see it. Five seconds per question, fifty for the round of twenty. Mistakes cost time. That's the price of a seal. Just the time and the expression. The rest is space for thinking. Yes. ¥350 unlocks all thirteen methods and all thirteen ranks. No subscriptions, no in-app purchases. Yes, from upper elementary…from indian-mathmatics.app

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
