LESSON 1. Numbers and
Measurement
Time and space in
the Universe has been here long before humans. However, some individuals have
questioned their surroundings. Many of these early philosophers wanted to
understand their world. They realized that in order to compare objects they
needed a way to create a symbol that represented discrete units so they
can compare it to other units. Modeling helps to predict outcomes
and develop a system that can be repeated. The systems could be used
in marketing, finance, economics, music, or science.
 Modeling
and using the correct symbols is difficult in the abstract. For
instance, if you have two apples and
three oranges, can you get five lemons? The equation would be 2 + 3 = 5, but
because of the equal sign you cannot
mix apples and oranges! If you have one worm and you add another worm you
have two worms. You can symbolically write it as 1 + 1 = 2, and you can
imagine it in your head. However, could we have another situation that
creates a two headed worm? No. If we could add numerals like that,
mathematics would be even more difficult than it is now!
