How to do fractions?

Introduction to how do you do fractions:

In this section let me help you understand on how to do fraction. Fraction is a certain part in a whole thing. Fraction is represented by a numerator and denominator. The upper part of the fraction is called as numerator and the lower part in the fraction is called denominator. Fraction can be added, subtracted, Multiplied and divided. These are the basic operation we do with fraction.

Classification of Fractions:

Fraction are classified as

* Proper fraction
* Improper fraction
* Mixed fraction. This could also help us on thermometer worksheet

Help on Numerator

Introduction to Numerator:

In this lesson let me basically put down on numerator which will help you on understand better.

* In general, the term numerator is defined as follows,
* A numerator is a number written over the line in a common fraction which is identified the total number of parts in the whole part like as2 in ½.
* Mathematically, a fraction contains dividend and divisor. Thus the dividend of fraction is called numerator.
* A numerator is a number in a fraction. Also it is called as nominator.
* The place of top number of a fraction is named as numerator.

Numerator Example:

Adding proper fractions for numerator:

Step1: verify whether the denominators are the similar or not (If not means, get LCD by cross-multiplying)

Step2: Add the numerators and locate the result on the same denominator

Step3: Finally decrease the fraction (if needed)

Example: This could also help us on perpendicular bisector

Find the numerator: 1 / 7 + 1 / 7

Step1: Fraction of both denominators is the same.

Step2: Add the numerators

1 / 7 + 1 / 7 = (1+1) / = 2 / 7

Step3: No need of reduction

2 / 7 = 2 / 7

So the final numerator is 2.

Importance of Statistics

Definition:

In this lesson let me help you on importance of statistics with the help of following definition. Statistics is the formal science of creating well-organized use of mathematical data between the groups of individuals. We can study the statistics with help of online tutors. So the online is very helpful to clarify the doubts. Now we will see the definitions and example problems that help with statistics online tutor.

List of Important definitions:

* Population
* Sample
* Variable
* Independent variable
* Dependent variable
* Data
* Statistic
* Parameter

Example 2:

Find the mode of the following sequence of numbers, 55,19,64,88,55,60. This can also help us on what is velocity.

Solution:

The given numbers are 55,19,64,88,55,60.

In the series the number ‘55’ should be occurring twice. Thus, the mode value is 55.

The solution is 55.

Introduction toGeometry Formula Sheet

Introduction to geometry formula sheet:

In mathematics, Geometry formula sheet contains formulas which are deals with size and shape of planes, points, solids etc. In geometry, points are Zero-dimensional shaped one which means the height, length, and width is not here. Line is nothing but a one-dimensional figure.

Examples from Geometry Formula Sheet:

This can also help us on factors of 35

Example 1: Find the area and perimeter value of for the followings?

1. Square, a = 12

2. Rectangle, l = 4 and w = 11?

Solution:

Area and perimeter formula for square is,

Area = a2

Perimeter = 4a

Area = 122

Area = 144

Perimeter = 4a

Perimeter = 4 *12

Perimeter = 48

Area and perimeter formula for Rectangle is,

Area = lw = length x width

Perimeter = 2(l +w)

Area = 4* 11

Area = 44

Perimeter = 2(l +w)

Perimeter = 2(4 +11)

Perimeter = 2* 15

Perimeter = 30

Note on Frequency Distribution

Introduction about Frequency Distributions:

In this section we are going to learn on Frequency Distribution. A Frequency Distribution defines us a summarized accumulation of data divided into commonly exclusive classes and the number of appearance in a class. Example: To show election result, income of people for a certain region, sales of a product within a certain period, student loan amounts of graduates, etc.

Types of Frequency Distributions

* Simple frequency distributions.

* Cummulative frequency distribution.

* Grouped frequency distribution.

* Cummulative grouped frequency distribution.

Procedure for Frequency Distributions:

To create frequency distributions from this data we go head as follows:

This will also help us on fraction simplifier.

1. Observe the highest and lowest value in data. Create a column with the title of the variable what we are using. Include the highest score at the apex of the column and include all values from the highest score to the lowest score.

2. The frequency distribution is finished by creating a tally column and the frequency value shown in tally column.

3. The total frequency for the distribution is recorded at the bottom of the frequency column.

Note on Decimal Calculator

Introduction to Decimal Calculator:

Calculator is a device which calculates the required process in that device and also we can substitute the many values in the calculator. Decimals is a number which is indicates the number with the point representation. In decimal number we have the point indication in between the numbers

Steps involved in calculator:

Step 1: Place the decimals multiplicand which is going to multiply and the multiplier in one after another and draw a horizontal line.

Step 2:Now we have to forgot the decimal point and do like a normal multiplication from left to right. This can also help us on pythagoras theorem proof

Step 3: And keep the remainder with next digit and add after then the multiply.

Step 4: In final step we have to add the decimal point value in both multiplicand and multiplier and keep remember to place decimal point in result in added place from left to right.

Introduction to adding radicals

Introduction to learn adding radicals:

Radicals are defined as the terms which are having the root. The roots present in the radicals are having either square root or cubic root or any other root. There are three terms present in the expression of radicals. One of them is radical symbol, another one is index and another one is called as the radicand. Example: 3√9 is known as the radical expression.

Explanation for Learn Adding Radicals

The explanation for learn adding radical are given in the following,This will also help us on radicals in algebra
* The expression of radicals consists of the number terms and the variables terms.
* Most of the arithmetic operations are done in the expression of radicals.
* If suppose the expression of radicals are having the square roots then we have to raise the power of even to the number.
* If suppose the expression of radicals are having the cubic roots then we have to raise the power of odd to the number.

Note on Commutative property

-->

Commutative property is always seen as an important one since it plays an important role in mathematics. Let me show you the main importance of this topic. At the end if you have any suggestion to make feel free to leave your comments on this.

If a and b are any two integer then a+b = b+a.

In other words, the sum of two integers remains the same even if the order of integers (called addends) is changed.

Verification : In order to verify this property, lets us consider some pair of integers and add them in two different orders. We find that the sum remains the same (integer).

Consider the following :

Integer(a) Integer(b) Sum(a+b) Sum(a+b)

5 7 (5+7)=12 (7+5)=12

[Here we observe that 5 is an integer as well 7 is also another integer and now if we add these two integers then the sum of 5+7=12 is also an integer and again similarly if we interchange in place of 5 if we put 7 and in place of 7 we put 5 then also the sum of both the integers will be same 7+5=12].

5+7 =7+5

Integer(a) Integer(b) Sum(a+b) Sum(a+b)

-5 0 {(-5)+0)}=-5 {0+(-5)}=-5

[Here we observe that -5 is an integer as well 0 is also another integer and now if we add these two integers then the sum of (-5)+0=-5 is also an integer and again similarly if we interchange in place of -5 if we put 0 and in place of 0 we put -5 then also the sum of both the integers will be same 0+(-5)=-5].

(-5)+0 =0+(-5)

Integer(a) Integer(b) Sum(a+b) Sum(a+b)

-5 -7 (-5)+(-7)=-5-7=-12 (-7)+(-5)=-7-5=-12

[Here we observe that -5 is an integer as well -7 is also another integer and now if we add these two integers then the sum of (-5)+(-7)=-12 is also an integer and again similarly if we interchange in place of -5 if we put -7 and in place of -7 we put -5 then also the sum of both the integers will be same (-7)+(-5)=-12].

(-5)+(-7) = (-7)+(-5)

-5-7 = -7-5
