Five subjects. One approach. No fluff. Every book starts with the idea, not the formula β uses real examples, not abstract ones β and respects your intelligence without assuming your background.
These are ebooks. PDF files you download the moment you pay and read on a phone, tablet, laptop or printed out. Nothing is posted to you.
You get the intuition first β what's actually happening β and the formula shows up afterward, as the natural way to write it down.
Speedometers, MRI machines, GPS signals, audio waveforms. If an example couldn't exist outside a textbook, it doesn't make the cut.
Written for someone smart who was taught badly β not someone who needs to be talked down to. No gatekeeping, no condescension.
Recommended order: Algebra β Geometry β Trigonometry β Statistics β Calculus. Or skip straight to whichever one's been bothering you.
Derivatives, integrals, limits β explained from scratch. Why the speedometer is a derivative calculator. Why MRI machines are calculus made visible.
You stared at 2x + 5 = 11 and wondered why there's a letter in your math. A variable is a placeholder for a number you haven't found yet β once that clicks, the whole subject changes.
Shapes, measurement, and the Pythagorean theorem β eight connected tools for describing and measuring the physical world. Built for anyone who's ordered the wrong amount of flooring.
You were handed SOH-CAH-TOA, told to memorize it, and never told why. Trig is the mathematics of angles β and angles are in every GPS signal, sloped roof, and audio waveform.
Statistics can be used to prove anything β that's not a flaw in the subject, it's a flaw in how it gets used. This book gives you enough of the real thing to tell the difference.
Most people don't buy a math book. They buy hours of someone else's time, one confused session at a time. Here's roughly what catching up on five subjects looks like either way.
Filling in the parts of school math that never quite landed the first time around.
Helping with homework without having to relearn it from a 15-year-old textbook.
Wanting to actually understand how the different branches of math connect to each other.
5 ebooks. 77 pages. Worked examples and answers in every one. Yours for one flat price, no subscription.
Get all 5 books β $47 βοΈPhysics, Biology, Chemistry and the Spanish edition β same approach, five books each, $47 each. Plus Mechanical Engineering and every title on its own at $19.99.
The Biology Bundle, the Chemistry Bundle and several new ebooks just went live. Get an email when new ebooks launch β at the launch price, before it goes up β and tell me which subject should come next.
There’s a confirmation email on its way β click the link in it and you’re on the list. I read every suggestion, and if enough people ask for the same subject, it gets built next.
