IMPORTANCE OF STUDYING MATHEMATICS
The most frequent word one hears today in all
education and business circles is STEM. We need to
educate all students in the fields of science, technology, engineering and
mathematics (STEM) in order to be competitive in the 21st century
global economy. This issue has gained significant momentum over the last few
years and is reaching critical mass but we still have a long way to go in
raising the level of our education and student achievement in these fields in
order to fulfill the increasing demand for qualified employees our corporations
and universities need in the Information Age.
Few
reasons why math is important:
1. Good for your brain
Research conducted by Dr. Tanya Evans of Stanford University indicates that children who know math can recruit certain brain regions more reliably, and have higher gray matter volume in those regions, than those who perform more poorly in math. The brain regions involved in higher math skills in high-performing children were associated with various cognitive tasks involving visual attention and decision-making. While correlation may not imply causation, this study indicates that the same brain regions that help you do math are recruited in decision-making and attentional processes.
2. Tell time
“I’m late, I’m late for a very important date.” – White Rabbit from the movie Alice in Wonderland. Don’t let your ignorance of math make you like the White Rabbit! A recent study indicated that 4 out of 5 children living in Oklahoma City can’t read the hands on an analog clock to tell time. Knowing math, and particularly fractions, can help you better tell time. While analog clocks may eventually become obsolete, don’t let your ability to tell time become outdated! Use your knowledge of fractions to help you tell time on analog clocks that have an hour, minute, and (sometimes) second hand.
3. Help in finances
Math can be helpful for balancing your budget because you will have a good understanding of how to make sure that your costs are less than the money you have. Balancing one’s bank account, for example, is an important life skill that requires math in order to subtract balances. People who know math are therefore less likely to go into debt because they did not know how much money they had versus how much money they spent.
4. Better cook (or baker)
With knowledge of math, for example, you can quickly deduce that a half-cup of flour is the same thing as eight tablespoons of flour. This skill can prove handy if you find that your half-cup measure is missing. Likewise, if you are cooking from a recipe that serves four people, but you need to feed eight people, your math skills tell you that you can simply double all of the necessary ingredients. Without math, you may not have enough food (or have too much food) to feed your guest!
5. Problem-solving skills
Math helps us think analytically and have better reasoning abilities. Analytical thinking refers to the ability to think critically about the world around us. Reasoning is our ability to think logically about a situation. Analytical and reasoning skills are essential because they help us solve problems and look for solutions. While it may seem far-fetched to believe that solving the train problem above can help you solve a problem in your life, the skills that you use in framing the problem, identifying the knowns and unknowns, and taking steps to solve the problem can be a very important strategy that is applicable to other issues in life.
6. Practically every career uses math in some way.
Obviously, mathematicians and scientists rely on mathematical principles to do the most basic aspects of their work, such as test hypotheses. While scientific careers famously involve math, they are not the only careers to do so. Even operating a cash register requires that one understands basic arithmetic. People working in a factory must be able to do mental arithmetic to keep track of the parts on the assembly line and must, in some cases, manipulate fabrication software utilizing geometric properties (such as the dimensions of a part) in order to build their products. Really, any job requires math because you must know how to interpret your paycheck and balance your budget.
7. Math is all around us and helps us understand the world better
To live in a mathematically-driven world and not know math is like walking through an art museum with your eyes closed. Learning and appreciating math can help you appreciate things that you would not otherwise notice about the world. In reality, math is everywhere! Don’t believe me? Read on for some examples of math in nature.
Bees, masters of geometry, use hexagons to build their honeycombs. The Fibonacci sequence, a famous sequence of numbers in mathematics, is found throughout nature: in pinecones, seashells, trees, flowers, and leaves.
The number pi can also be observed all around us. Pi is a cool number with many unique properties. Pi is approximately 3.14, but in reality, it is greater than 3.14, with an infinite string of numbers after the decimal point. Because pi is, in reality, an infinitely long number, it is expressed as the Greek letter pi (Ï€). It cannot be expressed as a fraction; numbers that cannot be expressed as fractions are said to be irrational. Pi is also transcendental, which means that it is non-algebraic; this means that pi cannot be the solution of single-variable polynomial equations whose coefficients are all integers. (By definition, all transcendental numbers are also irrational.)
The number pi can be observed in the shapes of rivers. The ratio of a river’s length to the distance from the source to its mouth is called the “meandering ratio.” The average meandering ratio of rivers approaches the number pi. It makes sense that the average meandering ratio of rivers approaches pi, because rivers tend to bend into loops, which are circular in nature. The ratio of a circle’s circumference to its diameter is also equal to pi.
Now that you know more about pi and about how math governs nature, don’t you feel that you have a greater command over the mathematical laws of the universe? It can be empowering to learn about mathematical principles because it can help make sense of a world that, oftentimes, does not make much sense.
8. Math can make you more popular
Before you start to disagree with me, think about how great it is to go to dinner with a friend who can quickly divide a check in their mind to determine how much each person needs to pay to split the bill. Your knowledge of fractions can also help you divide a pizza among a few people. While math is popularly the realm of nerds, your ability to avoid awkward confusion and silence as you and your friends try to divide a pizza or a dinner bill is a truly valuable skill. Be known as the cool (yes, I said cool) person that knows how to do mental math quickly!
9. Math can help you shop for a good sale
Not only will your quick mental arithmetic skills help you become known as the smart person who everyone appreciates when the waiter brings the check to your table, your math skills can also help you shop. Knowledge of percentages and how to calculate them quickly can help you save time when shopping at a sale at the mall – for example, to quickly calculate a discounted price, or to determine whether you’ve been correctly charged when paying for a shirt at the store. You don’t need a Ph.D. in math to develop some quick mental arithmetic skills; they can help you in these and other areas of your life in the long run.
Tip: use the 10 rule while sale-shopping. If you want to brush up on your math skills to be a better bargain-hunter, remember this rule: to subtract 10 from a price, you can just move the decimal place to the left by one digit. Take, for example, a shirt that has a price of $25.00 and is on sale for an additional 20 off. You can move the decimal over to the left by one digit to calculate 10 off – $2.50. Since 20 off is 2 x 10 off, you can quickly multiply $2.50 x 2 to get the discount amount – $5.00. Subtract the discount amount from the original price of the shirt: $25.00 – $5.00 = $20.00. You can use the 10 rule to quickly calculate 10 of the price and multiply it by a factor that can help you estimate price discounts quickly.
10. Math is a universal language
Sure, it’s mostly equations, numbers, and some Greek letters, but math is understood the same virtually all over the world (and who knows, maybe all over the universe)! A math equation doesn’t need to be translated to another language to be understood by someone on the other side of the planet. A mathematical law doesn’t change because someone has a different religion than you or speaks a different language from you. 2 + 2 = 4 in every single place on planet Earth. Pretty cool! The universality of math is one of the many things that makes it such a powerful tool and, indeed, essential life skill.
In summary, math is not only important for success in life; it is all around us. The laws of mathematics are evident throughout the world, including in nature, and the problem-solving skills obtained from completing math homework can help us tackle problems in other areas of life. While many may complain that math is boring or complicated, the truth is that a life devoid of math means that we go around experiencing the world on a much less interesting level than we could.
