RATIONAL NUMBERS

A number that can be expressed in the form p/q, where p and q are integers and q≠0.
All integers and all fractions are rational numbers.
A rational number is said to be in its standard form if its denominator is positive and its denominator and numerator are prime to each other.
0 is also a rational number, but it is neither positive nor a negative rational number.
Rational numbers are closed under addition, subtraction, multiplication and division (provided divisor is not 0).
The commutativity of addition as well as that of multiplication is true for rational numbers i.e. if a/b and c/d are any two rational numbers, then a/b + c/d = c/d + a/b and a/b × c/d = c/d × a/b
The associativity of addition is true for rational numbers i.e. is a/b, c/d and e/f are any three rational numbers, then (a/b +c/d) + e/f = a/b + (c/d + e/f)
Subtraction is neither commutative nor associative for rational numbers.
Commutativity and associativity of division is not true for rational numbers.
The sum of 0 and any rational number is the rational number itself i.e. if a/b is any rational number, then a/b + 0 = a/b.
The result of subtracting zero from a rational number is the rational number itself i.e. is a/b is a rational number, then a/b – 0 = a/b.
The negative of a rational number p/q is –p/q.
P/q and –p/q are called negative (or additive inverse) of each other.
Zero is the identity element for addition of rational numbers.
The product of 1 and any rational number is the rational number itself i.e. if p/q is a rational number, then p/q × 1 = p/q
The product of 0 and any rational number is 0 i.e. p/q × 0 = 0.
If a/b and c/d are two rational numbers such that a/b × c/d = 1, then each is called the multiplicative inverse or reciprocal of each other.
Zero has no reciprocal.
We can get countless rational numbers between any two given rational numbers.
If x and y are two rational numbers, then (x + y)/2 is a rational number between x and y such that x < (x + y)/2 < y.

LINEAR EQUATIONS IN ONE VARIABLE

An equation is a statement of equality which contains an unknown quantity.
In an equation, the expression on the left of the equality sign is the Left-Hand Side (L.H.S). The expression on the right of the equality sign is the Right-Hand Side (R.H.S).
Any value of the unknown, which makes L.H.S and R.H.S equal, is called its solution or not.
The process of carrying terms from one side to another is called transporting.
We can transpose a term from one side of an equation to the other side b merely changing its sign.

COMPARING QUANTITIES

The ratio of two quantities, say a and b, in the same units a/b and written as a : b.
A ratio is said to be in the simplest form, if the first and the second temr have no common factor, other than 1.
Ratio has no units.
An equality of two ratios is called proportion.
A fraction with its denominator as 100 is equal to that much per cent as much is the numerator.
x/100 = x%
To change a fraction into a per cent, we multiply the fraction by 100.
The money paid by the shopkeeper to buy an article is called its cost price.
The money received by a shopkeeper on selling an article is called its selling price.
Actual cost price = cost price + overhead charges.
The money which is borrowed, is called principal.
The period for the money is borrowed is called interest.
The total money which is paid after the expiry of the time is called the amount.
Amount = Principal + Interest
If we denote principal by P, rate by R and time by T, then Simple Interest = (P×R×T)/100
When the interest is added at the end of the year to calculate interest for the next year, the interest so obtained is called Compound Interest (C.I.)
The period after which the interest is added to the principal is called the conversion period.
The compound interest differs every year but simple interest remains the same.
If ‘A’ stands for the amount, ‘P’ stands for period, ‘R’ stands for rate and ‘n’ stand for number of conversion periods, then A = P (1+R/100)

EXPONENTS AND POWERS

If m is a positive integer and a is a rational number, then
- a^m= a x a x a x a ........ (m factors)
a^m is called the mth power of 'a'. Here 'a’ is called base and 'm' is called exponent.
A power with negative exponent (a^-m) can also be expressed in terms of a power with positive exponent having the same base 'a' as 1/a^m.
For any non-zero integer a, a^m x aⁿ = a^m+nWhere m and n are natural numbers.
For any non-zero integer a, a^m/aⁿ = a^m-nwhere m and n are natural numbers and 'm > n'.
If 'a' and 'b' are non-zero integers and 'm', 'n' are any integers, then
- (a^m)ⁿ = a^mn
- a^m x b^m = (ab)^m
- a^m/b^m = (a/b)^m
(1)^m = (1)ⁿ, for any integer m and n.
For any rational (non-zero) number 'a', we have a⁰ = 1
For comparing very large numbers or very small numbers, we have to change them in standard forms.

FACTORISATION

The process of expressing a polynomial as a product of two or more polynomial of smaller degree is called factoring polynomials.
Various types of polynomials to be factorized:
Polynomial each of whose terms contains a common monomial factor am* bm * cm = m(a + b + c)
Trinomial as a perfect square.
x² + 2xy+ y² = (x + y)²= (x + y) (x – y)
x² – 2xy + y² = (x – y)²=(x – y) (x - y)
Polynomial as the difference of two squares.
- x² – y² = (x + y) (x – y)
Second degree trinomial ax² + bx + c = (x + p) (x + q) where p + q = b and pq = c
A monomial multiplied by a monomial always gives a monomial. But a monomial divided by a monomial may not give a monomial.
Expressions having variables in the denominator, are not polynomials.
Expressions in which variables occur under root signs are not polynomials.
If the remainder is zero, both, the divisor and the quotient, are factors of the dividend.

PLAYING WITH NUMBERS

Think of any two-digit number and reverse it. Add the two numbers. Divide the sum by 11. The quotient will be equal to the sum of the digits of the number that was thought.
Think of any two-digit number and reverse it. Subtract the smaller number from the larger. Divide the answer by 9. The quotient will be equal to the difference in digits of the number which was thought.
Think of a three digit number. Write it by reversing the digits. Find their difference. Now this Difference + 99 = Difference between the hundreds digit and ones digit.
A number is divisible by 10 just when its ones digit is 0.
If we subtract the ones digit of a number from that number, the portion left over is a multiple of 10.
If the ones digit of a number is 0 or 5, then it is divisible by 5.
If the ones digit of a number is even, then the number itself is even.
If the ones digit of a number is odd, then the number itself is odd.
If the sum of the digits of a number is divisible by 9, then the number is divisible by 9.
If the sum of the digits of a number is divisible by 3, then number is divisible by 3.
If a number is divisible by both 2 and 3, it must be divisible by 6.
A number is divisible by 4, if the number formed by tens and units digits is divisible by 4.
A number is divisible by 11, if the difference of the sum of digits at even places and the sum of digits at odd places (beginning from units place) is either 0 or a multiple of 11.
A three-digit number is a multiple of 11, if the sum of its outer two digits minus its middle digit is a multiple of 11.

VISUALISING SOLID SHAPES

1. A polyhedron is a solid that is bounded by polygons which are called its faces. The faces meet at edges which are line segments. The edges meet at vertices which are points.
2. A polyhedron is convex if any two points on its surface can be joined by a line segment that entirely lies inside or on the polyhedrons.
3. A polyhedron is said to be regular if its faces are made up of regular polygons and the same number of faces meet at each vertex.
4. A prism is a polyhedron, two of whose faces are congruent polygons in parallel planes and whose other faces are parallelograms.
5. A pyramid is polyhedron whose base is a polygon (of any number of sides) and whose other faces are triangles with a common vertex.
6. According to Euler's formula, the relation:
- [Number of faces (f)] + [Number of vertices (v)] = [Number of edges (e)] + 2 is true for any simple convex polyhedron.
A map depicts the location of a particular object/place in relation to other objects/places
8. Maps use a scale which is fixed for a particular map. It reduces the actual distances proportionately to distances on the paper.
9. Visualising solid shapes (i.e., 3-D shapes) is a very useful skill which enables us to see its 'hidden' parts.
10. Various ways to visualise a solid shape are:
- by cutting or slicing the shape which would result in the cross-section of the solid.
- by observing a 2-D shadow of a 3-D shape.
- by looking at the shape from different angles, i.e., the front view, the side view and the top view.

DIRECT AND INVERSE PROPORTIONS

Two quantities x and y are in 'direct proportion', if they change together in such a manner that the ratio x/y remains constant.
Two quantities x and y being in direct proportion are written as x y.
Two quantities x and y are said to be in inverse proportion, if they change together in such a manner that the product xy remains constant.
If two quantities are in inverse-proportion then an increase in one causes a proportional decrease in the other (and vice-versa).
Two quantities x and y being in inverse proportion are written as x 1/y.

INTRODUCTION TO GRAPHS

Graphs represent a wide variety of data in an easy-to-read format for quick and ready comprehension.
Three useful kinds of graphs are
- Line graphs
- Bar graphs
- Circle graphs
Line graphs are usually used to show changes in amounts or results over a period of time.
Bar graphs are generally used to compare amounts or results. They are used to show categories which are different from each other.
Circle graphs are designed to show relative proportions. The angle of a sector of a circle is made proportional to the percent of an item of the data list to be displayed. They are used to represent data where all categories or groups are specified.
The position of a point on a plane is fixed by specifying its distances from two fixed lines perpendicular to each other.
In an ordered pair the x-coordinate is always stated first. The coordinates are always written in this order and thus they are called ordered pair.
