Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Decimals reveal a number's true identity.
Every real number is either rational or irrational — and the decimal expansion tells you which.
↳ If the decimal neither terminates nor repeats, the number is irrational — no exceptions.
Ratio of two integers — that's the whole story.
↳ The denominator q must never be zero — that single condition defines the set.
Squeeze a rational — there's always room.
Between any two rational numbers, there are infinitely many rational numbers — not just one.
↳ Density of rationals: no 'next' rational exists after any given one.
This SA-1 syllabus covers five core Class IX Maths units: number systems (rational vs irrational, decimal expansions, surds), polynomials (degree, zeros, factorisation, identities), coordinate geometry (quadrants, plotti…
~20 min · full explanation, examples & memory tricks in the app
20 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which of the following is an example of an irrational number?
Beginner$1.101001000\ldots$
$1.101001000\ldots$ is non-terminating and non-repeating, so it is irrational. The others are terminating or repeating decimals, hence rational.
How many rational numbers lie between $\frac{1}{5}$ and $\frac{2}{5}$?
BeginnerInfinitely many
Between any two rational numbers there are infinitely many rational numbers.
What is the coefficient of $x$ in $9x^2 + 4x - 6$?
Beginner$4$
The coefficient of $x$ is the number multiplying $x$, which is $4$.
Which of the following is a quadratic polynomial?
Beginner$ax^2 + bx + c$
A quadratic polynomial has degree $2$, so its standard form is $ax^2 + bx + c$.
