Most students learn maths by reading and watching.
Parhaylikhay teaches them by doing.
the difference
One side of this is how maths is taught.
The other side is what we built.
chapter 7 · circle theorems
The angle subtended at the centre of a circle by an arc is twice the angle subtended at any point on the major arc.
In the figure, ∠AOB = 110° at the centre, so ∠APB = 55° at the circumference for any P on the major arc.
fig. 7.1: angle at centre = 2 × angle at circumference
Reading. Watching. Hoping it sticks.
Doing. Exploring. Understanding.
Most platforms give students more textbook on a screen. Parhaylikhay gives them maths they can move with their hands.
the moment
Try it yourself. This is what every lesson on Parhaylikhay feels like.
+ 100s more
Hundreds of manipulatives like this. Every visual concept across O-Level Maths and Physics. Built so students learn by feeling the maths, not memorising it.
lesson mode
Inside every topic: a guided lesson that takes students from confused to clear, one interaction at a time.
What if every point moved the same distance in the same direction?
Drag the pink triangle until it lands on the dashed outline.
this transformation has a name
Translation
A transformation where every point of a shape moves the same distance in the same direction.
On the previous slide, you would drag a triangle by a vector. That move is called a translation.
Each lesson is 20–30 frames of pure interactivity. No passive videos. No walls of text. Just discovery, step by step.
checked, not memorised
Quizzes built for the topic. Not lifted from a worksheet.
We don't throw multiple-choice at every topic. Set theory gets a Venn you shade. Number patterns get a 1-100 grid you tap. The quiz fits the shape of the maths.
+ 100s more
A different quiz for every topic. Built so a student can't bluff through with pattern-matching.
and because cambridge marks are won and lost on specifics ·
Every lesson teaches not just the maths, but exactly what examiners reward.
Describe fully the transformation that maps shape A onto shape B.
for the transformation type, reflection.
for identifying the vertical mirror line.
for the correct equation x = 1.
15 years of Cambridge papers, integrated into how we teach. Not as flash cards. As the working we walk students through, every time.
this works for every visual topic
Transformations was one example. The platform teaches everything that's visual the same way.
circle theorems
Cambridge 4024 · 4.7
The hardest circle theorem, made obvious.
The angle between a tangent and a chord equals the angle in the alternate segment. Most students memorise the name; few really understand it. Drag the points, watch the two angles stay in lock-step.
nets of solids
Cambridge 4024 · 4.2
Unfold the solid. See the formula on every face.
Cuboid, cone, cylinder, prism, pyramid. Pick a solid and watch it open flat. Every face carries its own area formula. A student who unfolds it won't forget which faces to count.
3-D symmetry
Cambridge 4024 · 4.5
Every plane of symmetry, every axis of rotation.
Rotate the solid by hand. Each plane and axis lights up where it exists. Cuboid: three planes. Triangular prism: two planes. Cube: nine planes. Students see the count before they write the count.
angles at a point
Cambridge 4024 · 4.6
Angles all the way around add to 360°.
Drag any vertex. The four wedges resize together, and their sum stays exactly 360°. The student doesn't memorise the rule; they watch it hold.
centre of rotation
Cambridge 4024 · 7.1 · the hardest one
The perpendicular bisectors meet at the centre. Every time.
Cambridge's hardest transformation question: given the object and its 90° rotated image, find the centre. Walk the construction in six steps. Then drag any vertex or the centre, and watch the two bisectors swivel but always cross at the same point.
practice
15 years of Cambridge papers. Topic-tagged. Mark-scheme-aware.
Cambridge-marked questions, organised by topic.
Topical practice. Full mock exams. Smart review of weak areas. Spaced repetition built in. Students don't just learn. They prepare like the exam is tomorrow.
for teachers
Teach with the canvas. Not slides.
Every manipulative on Parhaylikhay is a blackboard a teacher can project, customise, and teach from. Pick any one. Reshape it on the fly. Walk the class through what changes when a number changes.

I just wish I had this when I was giving my O Levels.

Always hated maths. Never thought math would look this fun.

why this exists
I'm Hassan.
For years I watched brilliant students switch off in maths class. Their only fault, no one ever made them feel it.
I graduated in physics from University College London. Since then I've taught more than 800 students, one-to-one, in small groups, and in full classrooms. I have taught students across 7 countries, including from world-renowned schools like St Paul's School in Hammersmith, London. I'm also president and co-founder of The Tribe, a youth leadership ecosystem.
This is the platform I wish my students had.
