# Internet Service 'Mathematics Used in 100 Occupations' that Can Identify Mathematical Units Essential for the Work of the World at a Glance

Mathematics such as arithmetic calculations help us day by day such as shopping, but there are a lot of people who finish life without using trigonometric functions or differential integral. Blogger LM - 7 has published a net service " **Mathematics used in 100 occupations** " based on Hal Saunders' book " **When Are We Ever Gonna Have to Use This?** ". Looking at this net service, for example, you can see that "If you do not learn this unit of mathematics, it is difficult to get into this profession."

Net service: When accessing mathematics used in 100 occupations it is like this. In the leftmost pane items of items of mathematics unit line up with the slurry. From elementary mathematics in elementary school level such as "fraction" and "decimal" ... ....

When you scroll vertically, items such as 'matrix', 'trigonometric function / circle function', high school student level mathematics items, categorized 'mental arithmetic', 'mathematical communication' etc are listed side by side.

There are 100 kinds of occupations next to the pane of mathematical items. There are a number of occupations, from physics (research) to professionals where mathematics seems to be essential, such as veterinarians, ceramists, farmers, DJs, and many other professions. By default, it is set to master the unit of mathematics displayed in the left pane, so it is indicated that you can enter all 100 types of occupations.

To actually use it. As an example, I will try to say "Can not perform calculus and higher mathematics." When clicking the checkbox next to "calculus and higher mathematics", the × icon is displayed in the check box and it is set that you have not learned "calculus and higher mathematics". To check more than one item, hold down CTRL or Command key and click.

Then we can accommodate up to 91 different occupations from 100 kinds. "Physicists (research)" "computer programmers (real-time)" "aerospace engineers" "microwave engineers" "air quality engineers" "chemical engineers" "mechanical engineers" "electronics engineers" "biologists" Mathematics, "so you can not apply to these occupations.

By setting to not learn mathematics learned by high school students and higher, such as trigonometric functions, vectors and matrices, there are 57 types of occupations that can be employed in 100 types. To not learn mathematics means to abandon the possibility of getting into many occupations.

In addition, items arranged at the top of the table are also selectable, and when selected, the blue circle of that unit becomes highlighted, which makes it easier to understand which occupation is necessary. Try clicking "Vector", it looks something like this. Physicists (research), engineers, physicians, **chiropractors** are required to acquire vectors.

If you move the cursor to the blue circle icon on the table, you can check the items necessary for that occupation individually. Required if the "Required" item is true, unnecessary if false.

"Mathematics used in 100 occupations" is based on the survey conducted in the USA in the 1986s, so there are unnecessary units in Japan such as the yard / pound law, importance is more important than at the time such as a scientific calculator On the contrary, compared to that time, the importance of computer programming has not reflected the fact that the importance of computer programming has been raised, there are aspects that do not correspond to the change of the times, but the importance of mathematics is intuitive It has become a net service that can be understood.
