Real World Math
This site provides ideas and lessons for integrating Google Earth into the math curriculum; each
activity description is accompanied by a related downloadable Google Earth file
...

They can determine the area of such complex polygons as oddly-shaped crop fields
...
They can learn
about spherical geometry while measuring the angles of triangles constructed on a global scale
...
They can apply
formulas for the volume of solids while viewing and panning around the Great Pyramids and other
3D buildings
...
Everest

It’s almost impossible to get through a day without using maths in some way, because
our world is full of numbers to handle and problems to solve
...


There is no good, short answer to a question as general as this
...

Mathematics is a huge subject with a large number of sub-disciplines that is of great
importance throughout the natural and social sciences, in engineering and economics and
has important connections to philosophy
...
How
often have you heard a young learner utter the words, "I'm never going to use this
stuff!?" as they are struggling to solve some algebra or calculus problems? For many
parents and teachers, the utterance of this phrase (or ones like it) are too often a
common occurrence in the classroom
...
While these responses are good, and well intended, they don't serve the
practical and immediate needs of the child
...


Financial Management

Probably the single most cited practical application for math in our everyday life is for
money management
...
Ok, so I know what your thinking, "The
typical person who manages their own money has no need for math knowledge beyond
the basic concepts of arithmetic, right?" Well this is in fact incorrect
...
You see, the interest
(growth or payment terms) pertaining to these types of money markets utilize the
concepts of exponential growth
...


If you're serious about managing your money, you could even use higher math to
develop future projections of your spending habits
...

Below is a graph of my bi-weekly spending on groceries for the past year and a half
...
I can use the logarithmic equation to formulate an educated
guess of my future spending habits
...
As time progresses I am always
adjusting the equations so that they reflect the best possible chance to accurately
predict the future
...
Some basic math skills will enable you to determine how much
material you need to purchase to finish the project right
...
An electrician uses math to figure out how much wire they need to install
new electrical outlets
...
You will likely rely on some form of math even when you are
doing something as simple as painting a room
...


In terms of home improvement, math can also help the homeowner answer other
questions as well
...
This
could be equated to a dollar amount
...
With a little
math, and some numbers from your utility bill, you can easily calculate how much
money you spend leaving the lights on all the time
...
For fun, I thought I would do a
quick comparison of the cost of using a few different light bulbs to illuminate a room
...
72
$1
...
01
Cost Per 8 Hours
$0
...
12
$0
...
2 cents per kwh for electricity
The power of math enabled me to determine that the LED light has the lowest hourly
cost associated with it (this does not account for the initial purchase price of the bulbs)
...
If you have ever tried to reduce
your Body Mass Index by going on a diet, you've probably realized that counting
calories was a good way to monitor your food intake
...
Obviously
math can play a significant role in how someone progresses towards their weight loss
goals
...
Imagine how difficult the task of loading a barbell with
weight would be if you could not add or multiply numbers
...
Most will be
able to tell you what their one rep max is, as well has how much they can lift for a
variety of sets and repetitions
...

Fortuneatly, this is incorrect
...
Here's an example from
my personal life:

My car was low on coolant so I decided that I needed to fill up the reservoir with some
more
...
This was a problem as in most
cases coolant mixtures should be 50% water and 50% anti-freeze
...
5lbs
...
The equations are shown below:

(6
...
5lbs + Xlbs)(50% Water)

Reducing the equation:

(195)+(100X)=(6
...
6lbs

Therefore, I needed to add 2
...
With a little math I was able to solve the problem - No guessing or trips to
the store were needed!

Is that It?

The uses of math for the layperson are essentially endless
...
Personally I use math on a
daily basis to measure, track, and forecast many things
