Is your child struggling with Math — or just taught wrong?

I work with two kinds of students:

📘 School Math (Grade 6–12)
→ Most students don't lack intelligence. They lack foundations.
→ One weak concept in Grade 7 silently kills Grade 10 performance.
→ I find the gap. Fix it. Then build forward.

📗 Exam Prep (IB • SAT • AP Calculus • GCSE)
→ IB Math: Calculus + Stats = 60% of paper. We master these first.
→ SAT Math: 80% of questions test just 6 concepts. We drill those.
→ AP Calculus: Most students fail on FRQs — fixable with structure.

8 years. Hundreds of students across UAE, UK, USA & Singapore.

If your child is behind — or wants to get ahead — DM me.

@SpringerMath Algebra by Alexander Shen & I. M. Gelfand. Though, to be honest, it was more a great math teacher than the book itself that completely changed the way I looked at algebra.

Most students get this wrong on their first attempt.

Can you find the domain of this function?

Most people simplify too quickly and miss the hidden trap.

f(x) = (x² − 9)/(x − 3)

Which value can this function NEVER take?

Don't explain. Just comment your answer.

@teachergoals 😂😂😂 A much needed post.

📌 One of the most misunderstood concepts in functions!

Many students think Domain, Codomain, and Range are the same—but they're not.

Think of a function like a machine:

🔹 Domain → Every input you're allowed to give the machine.

🔹 Codomain → All the outputs the machine is designed to produce.

🔹 Range → The outputs the machine actually produces.

👉 Remember:
Range ⊆ Codomain
Understanding this distinction is essential for mastering functions, inverse functions, and higher mathematics.

MASTER FUNCTIONS SERIES

Not all functions behave the same way.

1) Some measure distance from zero (Modulus).
2) Some tell us the sign of a number (Signum).
3) Some jump from one integer to another (Greatest Integer/Floor Function).

Each function has its own unique graph, behavior, and applications.

Understanding these basic functions is the first step toward mastering algebra, calculus, and higher mathematics.

Which of these graphs looks the most interesting to you?

Those who bought Claude Pro because of the promises surrounding Claude Fable 5 and will they be getting a refund?

Many users upgraded based on the capabilities that were advertised. If the product delivered falls significantly short of those expectations, shouldn't there be accountability?

Paying customers deserve clarity on what was promised, what was delivered, and whether compensation will be offered for the gap.

@APA The research seems to have sampling bias. It is mainly studied in western countries (especially USA ). Thus it lacks ground for generalization.

@stats_feed I can see lots of hypotheses in comment but not even a single one have been tested and verified.

[Rishabh Tripathi @RishabhMathCore]

@AdityaRajS0212 @Math_files true

[Rishabh Tripathi @RishabhMathCore]

@mathhub_vn Another way

[Rishabh Tripathi @RishabhMathCore]

Most students fail this in 2 seconds.

Can a circle be a function? No.

Here is the test that proves it:
if a vertical line ever cuts a graph twice, it is not a function. y = x² passes. x² + y² = 4 fails.

Amazed to see that during COVID restriction there were 400+ million people travelled.

what is motive of this travel - business, migration, education, family, touring etc.?

Also is there chance of double counting as there are 90% of the world population has never been travelled through aeroplane.

@mathhub_vn Series is divergent can't be solved like this.
