*Math Used in the Workforce*

In the Work Force

Math can also be found in the workforce. For example:

- Construction Workers
- Everyone working in the critical field of construction, regardless of their particular area of expertise or specialty, will use mathematics on the job each and every day. From the simplest measurements to the most complicated fittings, algebra, geometry and trigonometry are necessary for workers in this industry to do their jobs successfully.
- Carpentry (e.g., scale factor, isoclines/lines of constant elevation, angular measurement and conversions, calculations with decimals and fractions, converting distance and direction into latitudes and departures)
- Construction Technology (e.g., unit conversions, Pythagorean theorem, sampling methods, right triangle trigonometry, volume of cylinders)
- Site Layout (e.g., angles and geometric figures; powers and square roots; unit conversions for lengths, areas and volumes; interpreting drawings)
- Project Supervision (e.g., bar graphs, network diagrams, rates of productivity)

- Cosmetology
- Hair Coloring - To effectively use hair color products, a beautician must use math to measure out products. Bleaching and dyeing is an exact process, with little room for mistakes. Too much bleach or developer can turn a blond color job into a frizzy, broken mass of hair. Color formulation is a specialty area in cosmetology. Careful measurement of tones is necessary to create the multifaceted hues that are popular with today's salon client. When applying color, geometry is a great help in sectioning hair for even coverage of base color and gray tones.
- Hair Cutting - The art of the good haircut is based entirely on geometry and trigonometry. All cuts are worked from a center point on the head, with parts, angles and layers drawn from that point. An off-kilter placement in the beginning means a crooked, unsightly cut. Precision and calculation relative to the straight plane is necessary for the ubiquitous bob haircut.
- Business - Cosmetology is a business that has many prices for different levels of service. To effectively charge clients, a salon owner must be able to graduate prices to get the most from every dollar. Each chair has to clear a certain amount of money to cover rent and other overhead costs.

- Astronomy
- By looking at objects in the sky with a telescope, the camera that is attached to the telescope records a series of numbers. The numbers correspond to how much light differential objects in the sky are emitting, what type of light, etc. In order to understand the information that these numbers contain, an Astronomer needs to use math and statistics to interpret them
- Forming and testing theories for the physical laws that govern the objects in the sky. Theories consist of formulas that relate to quantities to each other. For example, Newton's law, force = mass X acceleration) In order to be able to test these theories and use them to make predictions about what we will observe in the sky, astronomers need to use math to manipulate the equations.

- Lawyer
- when an attorney writes a brief for a case in which he has to convince the judge that his client should win the case, he structures it just like a geometric proof. He starts with all the given facts, then states the relevant laws and precedents that relate to the case. Then he makes his argument based on these facts using deductive logic, exactly as if he were doing a mathematical proof. The study of mathematics in which you have to prove theorems and properties using deductive logic is excellent training for a lawyer.
- most lawyers involved in civil cases in which people are suing others must be able to calculate percentages, interest, etc. to determine what is or isn't a fair settlement for the parties involved. Likewise, attorneys involved in tax or corporate law have to do a lot of computations involving money, interest rates, percentages and proportions.
- Patent attorneys who work on behalf of inventors generally must also have a degree in engineering because they have to be able to understand the inventions and the mathematical formulas involved in the physics or chemistry applications of the product.
