Problems Solving Method
Problem solving is like putting together a jigsaw puzzle. In the
case of textbook problems, all the pieces are present. Most just need to be
fitted together following the clues. In the case of real world problems, there
may be missing pieces or extra pieces, and no guarantee that the solution can be
done.
In solving a jigsaw puzzle, you fit the pieces
together, one at a time, one after another, in some order. The solution
follows an opportunistic path with pieces tried here and there, until done
or not. In solving a mathematics problem, the pieces to fit together are
collectively given by all the rules, methods & tricks you have met in
previous lessons and courses. A solution follows an opportunistic path
with pieces tried here and there, one at a time and one after another, until all
is done or not. Some pieces may be left-over. Each example or solution and each
proof or chain of reason met in mathematics may include a piece of
information, a trick, that you may recycle in further solutions. Once you know
the jigsaw approach or method for solving mathematics problems, rest is routine
and opportunistic. There is nothing more to problem solving than watching for
and collecting ideas or methods for opportunistic use. Can you do that?
First Hint: Master Logic
Problem solving is like putting together a jigsaw puzzle. In the case of
textbook problems, all the pieces are present and just need to be fitted
together following the clues, and an possible a picture showing the desired
result. In the case of real world problems, there may be missing pieces or
extra pieces, and no guarantee that the solution can be done.
Novice problem solvers should examine the following chapters in Volume 2, Three
Skills for Algebra.
- Two
Logic Puzzles
- Chains
of Reason
- Longer
Chains of Reason
- Islands
and Division of Knowledge
- Painless
Theorem Proving.
These appetizers and lessons show how rules and patterns may fit together to
arrive at conclusions or solve SOME problems. Problem Solving requires
precision reading and writing. Logic Mastery helps with that as well.
Second Hint: Master Fractions
Many applied mathematics problems involving chopping and combining lengths,
areas and volumes. So you need to know how to take a proper or improper
fraction of a length, area or volume. You need to understand that one
length may be 2.5 times or 2½ times or (5/2) times another. Any if you do
calculation, you need to do it with care or at least do it with the knowledge
that an error in one step makes all that follows wrong. The ability to figure
well and precisely, so that you answer is correct, shows or suggests the ability
to follow methods, one step at a time and one step after another in any subject,
and in problem solving as well.
Algebra Word Problems
one or more variables, that is the question.
If your interest is in solving algebra word problems at the high school
level, I would recommend learning how to solve linear equations in one to
several unknowns efficiently. The starting point for that could be the site area
Solving Linear
Equations with Stick Diagrams and chapters 8 to 15 in Three Skills for
Algebra.
High school students who can solve linear equations in one unknown are often
given word problems where extra variables have to be eliminated to formulate a
single equation in one unknown quantity to solve. The trick here is to draw or
extract a single equation from the given information. But in most such words
problems, it is easier to extract or draw from the given information several
linear equations in several unknowns to solve. Each sentence in the word problem
gives an equation in one or more unknowns or quantities. Now the algebraic way
of writing and thinking can be used to eliminate variables and to solve for the
one or more quantities of interest in an effortless fashion.
The algebraic solution of linear equations involves the elimination of
variables to obtain say one equation in one unknown. This elimination process
may be better done and recorded with algebraic notation. Going directly to one
equation in one unknown to solve a problem requires more work to be done with
words.
To learn more and to go further, see Solving
Linear Equations with Stick Diagrams and chapters
8 to 15 in Three Skills for Algebra.
PS. Being good in algebra and beyond requires an efficient command of
fractions, what they represent and how to work with them.
