“f(x + 2) and f(x) + 2 get treated as the same thing.”
Functions as objects
Domain, range, composition and inverses, treated as things you can do arithmetic to rather than as machines that eat numbers.

Lowest rate anyone charges
The year that decides how calculus goes. Nothing in it is famous, all of it is assumed later, and a shaky unit circle costs points for two more years.

What you’ll work on
Five things people say before they book.
One of them is usually the reason. The topic underneath is what a tutor would put the first month into.
/02
“Every trig value is a phone calculation, even the famous ones.”
The unit circle
Built once from thirty-sixty-ninety triangles, then known cold — because calculus never asks for it and always expects it.
/03
“Both sides of an identity get worked at once until they meet in the middle.”
Trigonometric identities
Which ones are worth memorising, which follow in one line, and how to tell a provable identity from an equation to solve.
/04
“Log rules are recited correctly and applied to the wrong term.”
Exponentials and logs
Logs as the question exponentials answer, the rules that follow from that, and the growth and decay problems that carry them.
/05
“A limit is read as a value the function reaches rather than approaches.”
Sequences and limits
The first sight of a limit, which is the idea the whole of calculus is written in and the one that most rewards early time.
None of them quite it?
Bring the syllabus, the textbook or the last score report to a first lesson. Every Pre-calculus tutor here plans against what you actually have, not against a standard course.
How a first lesson is runWho teaches it
Pre-calculus, taught by 3 of these 231.
In whichever order you find useful. Thirty minutes with any of them is free, so meeting two before you choose costs nothing but the evening.
What it costs
Priced by level, not by subject.
Tutors set their own rate and Saal adds nothing on top of it. These are the bands they set it inside, the same in every subject, and the lowest anyone charges to teach Pre-calculus is $34/hr.
Move or cancel any lesson up to twelve hours ahead at no charge, and the card is charged the morning after a lesson happens. Packages and refunds.

8 lessons a month, at $53 each — a 60-minute lesson against a rate quoted for 50. A ten-lesson pack takes $53 off that.
Your first thirty minutes
Thirty free minutes, and this is what they are for.
01
Sketch the unit circle
From memory, on paper. It takes ninety seconds and it tells the tutor most of what they need.
The terms, in full
- Free
- 30 minutes
- No card asked for
02
Work one function question
Composition or inverses, because that is where a student either has the idea or has a rule.
It will be one of these five
- Functions as objects
- The unit circle
- Trigonometric identities
- Exponentials and logs
- Sequences and limits
