If you write about math, physics, or code on Blogger, plain text falls short fast. You want real equations—integrals, fractions, matrices—not screenshots of LaTeX. KaTeX is a fast math typesetting library that runs in the browser. You load it from a CDN, write math in LaTeX-like syntax, and it renders cleanly on the page. No heavy setup, no image exports, no external equation editors. This guide shows a setup that works on Blogger (including custom domains). You’ll add a small HTML block once per post (or once in your theme), then write math with familiar delimiters. Demo (this page loads KaTeX): \[ f(x) = \int_{-\infty}^{\infty} e^{2\pi i \xi x}\, d\xi \] Inline: \( e^{i\pi} + 1 = 0 \). What you’ll need A Blogger post opened in HTML view (not Compose / rich text) Willingness to paste a small loader block at the top of the post Optional: the same block in your theme if you want math on every page How KaTeX works on Blogger (in one minute) Load the Ka...

If you’re looking for a math dice game that’s easy to set up and actually fun to play with friends, this one is worth a try. It’s a light challenge—enough to make you think, not enough to kill the evening. Four dice, a scrap of paper, and a few people who don’t mind scribbling or thinking out loud. I’ve played it around the table with friends: same target for everyone, same worker numbers, and a friendly race to see who can hit the number (or get closest). There’s usually more than one path, so you compare answers, laugh at near misses, and roll again. No board. No app. Just dice, a little arithmetic, and a bit of friendly competition. The idea in one breath Roll a target . Roll a few worker numbers. Use each worker once . Mix them with +, −, ×, or ÷ (and parentheses if you like). Closest to the target wins the round. That’s it. What you need 4 standard dice Paper and a pencil for each player (scratch paper is fine) 2 or more players (you can also play sol...
