Examples of Math in Everyday Life
Mathematics is one of the most important academic subject in student's study level. Mathematical ideas are more relevant and accessible in everyday life. Encouraging students in early life to deal with mathematical application makes them more comfortable and easier to face both subject wise and real life problems. Math offers students a variety of skills in a project that will add a new dimension to your math class. Our Nation is unlikely to remain a world leader without a better educated workforce.
Here are some of the places where we come up with a math application in every day to day life activity like time, sports and games,science,nature,building and construction, shopping,travel,etc.. Today world has been increased with the application of mathematics in every field. In commercially mathematics are used to analyze the discount rate, banking, ratio and proportion, stock management, etc.
The concept of average, mean, median, mode is followed in daily life like to study the rate of change,average speed of a car, number of rotations of planets around the earth, the study of molecular structure. A lot of research and development are carried out to prove the existence of theorems in real life.
Improving Maths Skills:
Each one of us simply can improve our mathematical skills by practicing, thinking things out. In school teacher can make use of chart, pictures, object ,etc for better understanding of the subject in lower grade levels. Students own formulas, key concept, ideas to be considered and appreciated for well development of student math skills. Mathematics idea more relevant and accessible work and in everyday life.

Question:I always hated math in school. Now that I'm older (26) I realize that I use most of those painfully acquired math skills all the time. Adding/subtracting fractions in cookery, decimals in money math, percentages and ratios for all kinds of things.
But... I honestly have never encountered a situation where I needed to solve a quadratic equation.
I understand that engineers, architects etc use algebra and graphing, not saying it's pointless, but can anyone please give me an example of when, say, a housewife would find algebra useful?
Answers:This is a hugely hypothetical situation, so don't laugh at the absurdity!
Say that you have $5 dollars in change, and you want to spend it all on turkey slices at the deli. But, because of taxes, you can't just get $5 worth of turkey. Let's say, for example, taxes are 12%, and turkey costs $1.11 per 100 grams (I have no idea if that's expensive or not, but let's just roll with it, for simplicity's sake!).
So, the equation for the grand total you'll need to pay for turkey is x + 0.12x = $5.00 : the 'x' being the amount actually spent on turkey (as in, before taxes) and the '0.12x' being the tax itself. If you combine the like terms, you'll get 1.12x = $5.00. Divide $5.00 by 1.12 will get you $4.46. This in itself doesn't mean much, until you divide it by the cost for each 100 grams of turkey. $4.46 divided by $1.11 is roughly 4, so if you ask for 400 grams of turkey, you'll pay approximately $5.00.
I know that's a weird, weird example. But in actuality, we use algebra everyday, just not in the same sense as we learned in school. In math class, algebra was always taught to us with one of the beginning terms as the unknown (the cost of turkey, or the tax), and the answer already known. In real life situations, we wouldn't often know the answer. If you're shopping, and you see a $10 shirt for 25% off, finding out how much it is after the discount is actually algebra: $10 - 25% of $10 = x .
Hopefully I didn't leave you more confused!
Question:Can anyone give me any ideas for some math concepts found in everyday life that is interesting? The topic is below:
Teach the class extension(s) of a mathematical concept occuring in everyday life. Some examples include: magic squares, number pi, tessellations, Fibonacci numbers in art or nature, math in music, architecture, etc.
If anyone can shout out more possible ideas, so I have a list to think about...hopefully I can pick one and start working on my presentation on that math concept. Thanks in advance to everyone!
Question:I need examples of longitiudinal, transverse and surface waves in everyday life (i.e you do this task that encounters or uses that type of wave).
thank you! I need about 3 for each type of wave.
light waves are all transverse electromagnetic waves
Sound waves travelling ON the surface of a medium are transverse eg: sound wave travelling along the surface of a table.....
A sound wave that travels IN or along the medium: eg: a wave travelling IN air or In water........
Examples of transverse waves include seismic S (secondary) waves, and the motion of the electric (E) and magnetic (M) fields in an electromagnetic plane wave, which both oscillate perpendicularly to each other as well as to the direction of energy transfer. Therefore an electromagnetic wave consists of two transverse waves, visible light being an example of an electromagnetic wave.
Examples of longitudinal waves are sound, ultrasound, and earthquake
a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities
Examples are the waves at the surface of water and air (ocean surface waves), or ripples in the sand at the interface with water or air. Another example is internal waves, which can be transmitted along the interface of two water masses of different densities.
Question:why are school teaching it to little 8-9 year olds and younger? another problem with schools i have, is when doing "real" everyday math, we were automatically told to use a calculator. now, ppl my age and younger, generally have problems handing back chance from registers, if having to think in your head. example: if working a concession stand, and the register does no tell you what to give back. i know this does not apply to everyone but who on here has the same issues and concerns about school? just wondering. correction- instead of "chance", i meant "change" in that sentence!
Answers:Algebra is used frequently in everyday life, but we don't often think about the fact that we are using algebra. If you are trying to figure out how many packages of hot dog buns to buy for a party, you are using algebra. Planning a budget for a road trip based on gas prices and gas mileage - using algebra.
As for why it's being taught as early as Kindergarten (yes, those old problems Square +1 = 2, what goes in the square? - algebra!), it's to develop algebraic thinking. Thinking about algebra means thinking in a unique way in which numbers combine not just in a forward 1+2=3 but also in a 3-2=1 or 2+1=3 way and so on. The sooner we introduce students to this form of thinking the more successful they will be with any type of logic problem presented to them, not just algebra.
However, I agree with you about calculators. It is important to teach students how and when to use calculators. It is also important to teach students how to estimate so they know if they made a mistake leading to a wrong answer on a calculator. Calculators can only be as good as the people using them.
