Example of Integers

An integer is a whole number .It can be positive, negative, or zero. The integers are natural numbers including 0 together with the negatives of the non-zero natural numbers .The the real numbers that can be written as   without a fractional or decimal component.

Properties:

Existence of an identity property                      m + 0 = m                                    m x 1 = m

Existence of inverse property                            m + (-m)=0

The ordering of integers with the algebraic operations

if a < b and c < d, then a + c < b + d
if a < b and 0 < c, then ac < bc.

Positive and Negative Integers

Positive integer are all the whole numbers greater than zero example: 1, 2, 3, 4, 5,... . Negative integer  are all the opposites of these whole numbers examples : -1, -2, -3, -4, -5, … . We don’t consider zero to be a positive or negative number.

For example:

-5 is the opposite of 5, -22 is the opposite of 22, and 8 is the opposite of -8

The Number Line

It  is a line labeled with the integers are increasing order from left to right, that extends in both directions.

Examples:

9 > 5,  6 > -10, - 2 > -5,  and  0 > -9

|6| = 6
|-122| = 122
|0| = 0
|-1234| = 1234
|-10234| = 10234

Adding Integers

Adding Integers

Adding integers of the same sign, we add their absolute values, and it give the result the same sign.

Example:

2 + 5 = 7
(-7) + (-2) = -(7 + 2) = -9
(-80) + (-34) = -(80 + 34) = -114

Adding integers of the opposite signs, take their absolute values, subtract smaller value  from larger value , and result the sign of the integer is  the larger absolute value.

8 + (-3) =5

Subtracting Integers

Subtracting an integer is the same as opposite of adding.

7 - 4 = 7 + (-4) = 3
12 - (-5) = 12 + (5) = 17
-8 - 7 = -8 + (-7) = -15
-22 - (-40) = -22 + (40) = 18

Multiplying Integers

A pair of integers if both numbers are the same sign, their product is positive. If the numbers are opposite signs, their product is negative. If one or both of the integers is 0, the product is 0.

-4) × (-5) = |-4| × |-5| = 4 × 5 = 20

(-7) × 6 = -42.

Basic Math Definitions

Addition means sum of two quantities. The sign used to do addition is ‘+ ‘.

If Joe has 2 black pencil and 3 blue pencil means then the total number of pencil is 2+3 that is 5 pencils.


Subtraction in math


Subtraction means difference of two quantities. The sign used to do subtraction is ‘– ‘.

If Kayla has 5 rupees and she spent 2 rupees in a store then the amount she has left in a hand is 5-2 that is 3 rupees.


Division in math


Division means sharing a number into equal parts. The sign used to do division is ‘/’.

If a mom has 6 chocolates and then if she wants to give those chocolates to 2 children means, then it is 6/2 that is 3 .So she will give 3 chocolates to each child.


Multiplication in math


Multiplication means a number is added to itself a number of times. The sign used to do multiplication is ‘x’ or sometimes ‘*’.

2+2+2=6 which is same as 3 times 2 which is equal to 6


Acute, Right and Obtuse angles in math


The angle which is less than 90 degree is an acute angle. For instance, we can say 45 degree is an acute angle.

The angle which is equal to 90 degree is right angle.

The angle which is greater than 90 degree is an obtuse angle. For instance, we can say 75 degree is an obtuse angle.


Ascending order and Descending order in math


Arranging a list of given elements from smallest number to greatest number is Asceding order.

Consider, the given list of numbers are 9,4,8,2 then the ascending order of a given list is 2,4,8,9.

Arranging a list of given elements from greatest number to smallest number is Descending order.

Consider, the given set of numbers is 9,4,8,2 then the descending order of a given list is 9,8,4,2.

Instant Word Problem

Introduction to instant word problem:

Instant word problems deal with solving algebraic word problems with the help of algebraic expressions and using basic algebraic functions.  Instant word problem comes under all the branches of mathematics. To solve the given instant word problems we need to derive the mathematical derivation. Here we are going to discuss algebraic instant word problems. The following are some of the example problems deals with instant word problems.


Instant word problem examples:


Example 1:

Jagan can do a certain work in the same time in which Raju and Somu together can do it. If Jagan and Raju together could do it in 10 days and Somu alone in 50 days, then B alone could do it in?

Solution:

(Jagan + Raju)'s 1 day's work = 1 / 10

Tom 1 day's work = 1 / 50.

(Jagan + Raju + Somu)'s 1 day's work     = {1/10 + 1/50}

= 5 / 50 + 1/ 50

= (5+1)/50

=6/50

=3/25--------------(1)

Jagan day's work = (Raju + Somu)'s 1 day's work .------- (2)

From (i) and (ii), we get: 2 x (Jagan ‘s1 day's work) = 3/25

Jagan ‘s1 day's work = 3/50

Raju ‘s1 day's work {1/10 – 3/50} = 1/25

So, Raju alone could do the work in 25 days.

Example 2:

Angle is thrice as good as worker as Marie and therefore he is able to finish a job in 60 days less than Marie. When they working together, how long they can do it in?

Solution:-

Given Angle is thrice as good as work man as Marie.

Therefore the ratio of work done Angle and Marie is 1: 3

If difference of time is 2 days, Marie takes 3 days.

If difference of time is 60 days, Marie takes (3/2 x 60) = 90 days.

So, Angle takes 30 days to do the work.

So Angle s one day work = 1/30

Marie one day work = 1/90

Now (Angle + Marie) one day work = (1/30 + 1/90)

The LCM of 30 and 90 is 90.

Now take LCM and add we get

= 3 / 90 + 1/ 90

= (3+ 1)/ 90

=4/ 90

=2/45

Angle and Marie together can do the work in 45 / 2 = 22 ½ days.


Practice instant word problem:


Ram can do a certain work in the same time in which Thanesh and Ram together can do it. If Ram and Thanesh together could do it in 20 days and Ram alone in 60 days, solve how many days did Thanesh alone do it?

Answer: So, Thanesh alone could do the work in 20 days.

Solving Doubling Time

Introduction to solving doubling time:

Let us see about solving doubling time. The standard time it gets for an exacting population to double size is known as it’s doubling time. This statistic is a coarse pointer of the fertility of a population. Doubling time is the fastidious time necessary for a quantity to double in size or value. Doubling time is largely applied to population growth, consumption of goods, compound interest, and many other things which tend to produce over time.

Formula for the Doubling Time:

Let us see the formula for doubling time.

`T_d = (log(2) / log ( 1 +( r / 100))) = 70 / r.`
