Why maths is easier on a board
Most maths confusion is one step that nobody showed you. A textbook prints the finished working; a video moves on before you've caught up. Litu works the problem out in front of you, one line at a time, and stops the moment you say "wait".
It draws the graph, the triangle or the number line as it explains, so you can see why the rule works instead of memorising it. When a sign flips or a term moves across the equals sign, Litu circles it and says why.
Questions you can ask
- Why does a quadratic have two answers?
- How do I know when to use sine and when to use cosine?
- What does a derivative actually measure?
- Why can't you divide by zero?
- How do I find the gradient of this line?
Topics Litu covers
- Number and algebra: indices, logarithms, surds, factorising, simultaneous and quadratic equations, inequalities, sequences.
- Geometry and trigonometry: angles, circle theorems, Pythagoras, sine and cosine rules, bearings, mensuration.
- Graphs and calculus: straight-line graphs, gradients, differentiation and integration.
- Statistics and probability: mean, median and mode, charts, cumulative frequency, simple probability.
For WAEC, NECO and JAMB maths
These are the topics on the senior secondary mathematics syllabus. Snap a past question from your textbook and Litu redraws it in chalk, then teaches the method so you can do the next one yourself. See how students use Litu for exam prep.
How a maths lesson goes
- Say what's confusing, in your own words, or snap the question.
- Litu works it out on the board and explains each line as it writes.
- It checks you've got it with a quick question, and goes over it again if not.
