Why is Math important? Well, it is the underlying factor in the majority of life.

While it may seem like math problems like the above have no real use in life, this couldn’t be farther from the truth!  Math is incredibly important in our lives and, without realizing it, we use mathematical concepts, as well as the skills we learn from doing math problems, every day.  The laws of mathematics govern everything around us, and without a good understanding of them, one can encounter significant problems in life.

Read on to learn a few reasons that math is a powerful and incredibly useful tool.

  1. Learning math is good for your brain.  Research conducted by Dr. Tanya Evans of Stanford University indicates that children who know math are able to recruit certain brain regions more reliably, and have greater 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 attention processes.
  2. Math helps you 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 cannot 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  While analog clocks may eventually become obsolete, don’t let your ability to tell time become outdated!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. Math makes you a better cook (or baker).  With a 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 can prove handy if you find that your half-cup measure is missing.  Likewise, if you are cooking from a recipe that serves 4 people, but you need to feed 8 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 guests…
  4. Math helps us have better 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 important because they help us solve problems and look for solutions.  While it may seem farfetched to think 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 can be applied to other problems in life.
  5. Math is used in practically every career 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.
  6. 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 (π).  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 equation 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.

  1. 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 truly a valuable skill.  Be known as the cool (yes, I said cool) person that knows how to do mental math quickly!
  2. Math can help you shop 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, but 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 PhD 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.

Math skills can be pretty helpful!

  1. Math is the 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.

Math problem answers:

A1. Two apples

A2. To solve this problem, simply divide the distance travelled for each train by its speed to obtain the time that the journey will take.  Assuming that the trains travel a uniform velocity and make no stops, The Boston train will arrive in Kansas City in (1450 / 50) = 29 hours. The San Francisco train will arrive in (1850/40) = 46.25 hours. 

To calculate the time difference, simply subtract 46.25 from 29 = 17.25.

Therefore, the Boston train will arrive first – and the San Francisco train will arrive 17.25 hours later.

A3. The circumference of a circle is equal to the diameter of the circle times pi. Therefore, dividing the circumference (2π) by π gives us the diameter, which is 2.  The radius is half the diameter, so in this case, 2/2 = 1.  Therefore, the radius of a circle with circumference 2π is equal to 1.
