## Math Editor.

Introduction to the field:

As a math Editor, your work will make an immediate impact on the lives of many people.

Publishers of the book change, adapt and refine the manuscripts of authors before publishing books, or before people can buy a copy to read.

Publishers of math do something similar, except that they help teachers to write, edit and publish mathematics textbooks used in schools, or public use.

The challenge:

Although your mathematical skills will be valued much by ensuring that all the theorems and formulae of meaning, the work involves much more than that.

An editor, you will be responsible for the Edition, in proofreading, formatting, to check the spelling, grammar and usage and to improve the style and content so that the information will be attractive to readers.

Get the job:

You want to be an editor of mathematics for Pearson education? McGraw-Hill companies? or Houghton Mifflin?

The minimum requirement to get a job as an editor of mathematics is a Bachelor’s degree in mathematics or a related field.

If you want to treat mathematics in advance, such as algebra, real analysis, a diploma of advanced studies in pure mathematics, or the teaching of mathematics, can probably give an advantage over other candidates.

Don’t forget that you will check theorems and formulas of precision in the manuscripts, so if you want to put your hands on materials in advance, it is logical to have a knowledge of the materials.

Almost all positions require experiments in high school, or level collegiate and knowledge of the development of education programs.

In addition, as mentioned above, you will need interpersonal skills and strong communication writing.

Don’t be surprised if a company asks you to take a test written in the process of hiring before they set up an interview.

This field is growing and there is not many people to do the work.Having a major math is also rare. Therefore, if you are interested in this field, your chances of getting a job are good enough. Be proud!

## Calculation of the batting average

When the effigy or the calculation of the average to the stick of a baseball player, simply use the following formula:

= (Number of hits) batting average / (number of official at bats)

As you can see, the batting average is just a report of the “number of times where the player hit the ball” on “at bat”.

More this average or more the average is 1, the player hits. Therefore, the above formula is a measure of how well the player hits.

In calculating this average, we tour usually decimal answers to three locations

Example # 1:

A player hits safely 34 times.

the player was at bat 45 times

What is the player batting average?

= (Number of hits) batting average / (number of official at bats)

= (34) Batting average / (45)

0.755555555555 = Batting average

After having doubled to three decimal places, we get 0.755

As you can see here, this is a very good score that have never met any human beings human.

Example # 2:

A player hits safely 15 times.

the player was at bat 30 times

What is the player batting average?

= (Number of hits) batting average / (number of official at bats)

(15) = Batting average / (30)

= 0.5 Batting average

After having doubled to three decimal places, we get 0.500

Example # 3:

A player hits safely 24 times.

The player was at bat 64 times

What is the player batting average?

= (Number of hits) batting average / (number of official at bats)

(24) = Batting average / (64)

= 0.375 Batting average

Ty cobb, one of the greatest at bat, has a record of 0.366

Example # 4:

A player hits safely 10 times.

The player was at bat 26 times

What is the player batting average?

= (Number of hits) batting average / (number of official at bats)

(10) = Batting average / (26)

0.38461 = Batting average

After having doubled to three decimal places, we get 0.385

## Professor of mathematics of Middle school

Introduction to the field:

To get a job as a Professor of mathematics at lycée, the steps are essentially the same as the steps to follow to become a Professor of mathematics at the secondary school.

You must become certified. To become certified, you must pass a test of the State to obtain a provisional licence. The State then gives you a valid license from 3 to 5 years.

For example, to become certified in mathematics, I took 2 tests. First of all, I took the test of mathematics and of communication and literacy skills. I spent all the tests, they have me a valid license for 5 years

In the meantime, they expect you to pursue a master’s degree in education to become fully qualified. There are certainly other paths. Some people fulfill all the requirements, to include masters at the University.

However, you can get a job without certification if there is a great need.Then, after you are hired, the State or school that you expected that you to obtain your certification as soon as possible.

If you have never taught before, your greatest challenge, more than any other, are your students.

Yes, students of College of education is probably the most difficult endeavor ever. No step to frighten, but prepare yourself!

College students enter the classroom with a variety of problems. Changes in hormones and physical they enter puberty is one of these problems and adolescents do not usually know how to deal with these changes, or even how to explain this to an adult.

Accordingly, they express their fear and emotion with anger, disruptive behaviour, breach of the laws and showing no respect for authority.

If in addition to this, you are Professor of mathematics school, things get better because for some mathematics can be their worst nightmare. In addition, many young people begins middle school with a lot of gaps in their learning

As I said, it is just my opinion. What works for me may not work for you. However, I have had experience as a Professor of mathematics of middle school and I found it very useful, do the following:

(1) Firstly be very ready to teach your class. This means that you should have a lesson plan established, ready to teach the class. Gift that you well lesson, no complicated jargon! Remember, if you are not prepared, then they will be prepared for you.

(2) Be still very humble and do not shout. If you are not respectful and you shout at them, you are simply their teacher who cried and be disrespectful, are the appropriate means to deal with frustration.

(3) Listen, listen, hear and listen to. At this age, they have many questions and concerns. Those who need solid answers.If you do listen to them and try your best to answer these questions, while they have no reason to listen.

(4) Be friendly, but don’t be a friend. If you do, you will create a user-friendly environment, lead to learning as opposed to the creation of a hostile environment, where students see you as an enemy.

(5) Be a resolver. Do not solve only problems of mathematics, but help your students also solve the problems they have between them.If you do that, be prepared to deal with that once more.

(6) Keep the consequences to a minimum. Consequences did not decrease the behaviours. How many of you had a speed ticket? You an even speed?If you say no, of course! Good communication between you and your students can help solve most problems of classroom behaviour.

Get the job:

It may be easier to get a job as a Professor of mathematics of middle school, as opposed to a secondary school or primary school more because school districts have problems to keep their teachers by the great challenge that this may sometimes involve.

You can now make an informed decision. For the high school of teaching mathematics, Professor of mathematics to see High school

In any event, be ready for a challenge, to make a difference and to teach with enthusiasm. Your joy will be huge if you get there!

## Calculate salary home

To calculate the wages of home, add simply all deductions and then subtract the total deductions from gross pay.

Definition of take home pay: also called net pay, wages of home is the money that remains after all deductions were exempted gross pay.

Definition of deductions: all the money from your gross salary

Definition of gross earnings: the sum of money paid to an employee before deductions

Take home pay = gross earnings – deductions

Example # 1:

Steve is a programmer and works 35 hours a week. Steve is paid \$25 / hour. Calculate salary home

Here are the payroll by Steve:

Federal tax: \$130

State fee: \$25

Health insurance: \$80

Health insurance tax: \$52

Disability: \$12

Dues: \$21

First, calculate the total deductions:

Total deductions = tax federal + state tax + insurance + tax for Medicare disability + membership dues

Total deductions = \$130 25 \$ + \$80 + 52 + 12 \$ + \$21

Total deductions = \$320

Second, calculate steve gross income:

Gross pay = number of hours worked × rate

Here is how much you get paid per hour

Thus, gross pay = \$35 × 25 = \$875

Take home pay = gross earnings – deductions

Take home pay =-320 \$ \$875

Take home pay = \$555

Example # 2:

Amy is a registered nurse and works 52 hours per week. Amy is paid \$50 per hour for regular time and \$75 per hour for overtime

Here are the payroll deductions to Amy:

Federal tax: \$150

State tax: \$54

City tax: \$24

Health insurance: \$100

Health insurance tax: \$45

contribution that: \$80

First, calculate the total deductions:

Total deductions = tax federal + state tax + tax + insurance + insurance + contribution tax

Total deductions = \$150 + \$54 + 24 \$ + \$100 + \$45 + \$80

Total deductions = \$453

Second, calculate steve gross income:

Gross pay = number of hours worked × rate

Given that Amy has worked 52 hours, there is overtime pay.

Regular pay = × 40 \$50

Regular pay = \$2000

The overtime pay = × 12 \$75 \$

The overtime pay = \$900

Gross pay = regular salary + overtime compensation

Gross pay = \$2000 + 900 \$

Gross pay = \$2900

Take home pay = gross earnings – deductions

Take home pay = \$ \$2900-453

Take home pay = \$2447

## Centroid of a triangle

The centroid of a triangle is the point where the three medians of a triangle meet or cross an illustration of the barycenter is shown below.

In the chart above, we call each line (in blue) a median of triangle.

The median is the line that starts with a vertex and goes in the opposite side

After you build the three medians, to the point where they cross (shown in red) is the centroid

Now, if you place a triangle on the coordinate system, you can easily get the barycenter in a simple calculation

Call the centroid C, the formula for the barycenter is:

[(1_x_+_x_2_+_x_3) / 3, (y1 + y2 + y3) / 3]

Example:

Find the centroid of triangle following with veetices (1,2), (3,4) and (5.0)

C = [(1_+_3_+_5) / 3, (2 + 4 + 0) / 3] = (9/3, 6/3) = (3.2)
