How to use the tutor guide

This guide is a bank of extra practice. For the lessons in the course, it has fresh problems built in the same shape as the ones in the textbook, so you can keep working a skill until it feels steady. Each problem comes with a full worked solution behind a reveal: try the problem first, then open the solution to check your reasoning, not just your final answer.

The quickest way to use it is with the tutor. Ask Claude for a few problems like the ones in Lesson 5.4, or quote a problem's code, and it will work through it with you and check the math. You can also read a unit's page here and work straight down it on paper.

Every problem carries a short code, like 5.4.T1. The T marks it as a tutor-guide problem, kept separate from the textbook's own numbering so the two never collide. Quote a code to the tutor to point at one exact problem.

Each unit ends with a mixed-review set, with codes like 5.R.T1. These mix skills from across the unit on purpose, so two problems in a row rarely call for the same first move. That kind of mixed, spaced practice feels harder than a page of look-alikes, and it's what makes a skill last to next week. Reach for a review set when a unit feels solid, or to warm up after a few days away.

The matching lessons, worked examples, and figures live in the textbook, and the student guide lays out the whole path through the course.
