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.
All numbers you know fit here.
The real number system includes all numbers on the number line. It is divided into rational and irrational numbers. Rational numbers can be written as a fraction $\frac{p}{q}$ where $q \neq 0$. Irrational numbers cannot be expressed as a simple fraction; their decimal...
↳ Every real number is either rational or irrational.
Expressions with many terms.
A polynomial is an expression of the form $a_n x^n + a_{n-1} x^{n-1} + \dots + a_1 x + a_0$, where $a_i$ are real numbers and $n$ is a non-negative integer. The degree is the highest power of the variable. For example, $3x^2 - 5x + 2$ has degree 2.
↳ Degree tells you the highest exponent in a polynomial.
Shortcuts for expanding expressions.
↳ Memorize these identities to factor and expand quickly.
This kit covers essential 9th grade math topics including the real number system, polynomials, linear equations, coordinate geometry, geometry, mensuration, and statistics. It provides key formulas, definitions, and prob...

17 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which of the following is an irrational number?
Beginner$\sqrt{2}$
$\sqrt{2}$ cannot be expressed as a fraction of two integers, so it is irrational. The others are rational.
What is the value of $(2^3)^2$?
Beginner$2^6$
Using the power of a power rule: $(a^m)^n = a^{m \times n}$, so $(2^3)^2 = 2^{3 \times 2} = 2^6$.
If $p(x) = 2x^2 - 3x + 1$, what is $p(2)$?
Intermediate$3$
Substitute $x=2$: $p(2) = 2(2)^2 - 3(2) + 1 = 8 - 6 + 1 = 3$.
The point $(0, -4)$ lies on which axis?
Beginnery-axis
A point with x-coordinate 0 lies on the y-axis. Here, $(0, -4)$ is on the negative y-axis.
