- Reading mathematicsThe shorthand itself: what a letter, a subscript, a counter and a summation sign stand for, so a formula can be read back into the arithmetic it abbreviates.2 lessons
- Powers and logarithmsRepeated multiplication, what the shorthand means once the count stops being a whole number, where the constant e comes from, and the operation that undoes it.2 lessons
- Angles and circlesGoing round a circle, the two coordinates that trace it, and what rotating a point does to the numbers that describe it.1 lesson
- Vectors and linear mapsLists of numbers treated as one object, the transforms that stretch and turn them, and why stacking those transforms gets you nothing new on its own.2 lessons
- DistributionsA list of shares that add up to one, what that one constraint buys you, and what a share does not tell you about what is going to happen.4 lessons
- Rates of changeHow sharply one quantity responds when you nudge another, how that response is measured, and what a slope can and cannot promise about anywhere but the point you measured it.1 lesson
- Big O notationWhy an algorithm's cost is written the way it is, and what each piece of the notation quietly hides.17 lessons
