SOLVING PROBLEMSSOLVING PROBLEMS
FAMILIARIZE yourself with the situation. If it
is described in words, read carefully. In any case,
think about the situation. Draw a picture
whenever it makes sense to do so. Choose a
letter, or variable, to represent the unknown
quantity. To be solved for.
TRANSLATE the problem to an equation.
SOLVE the equation.
CHECK the answer in the original wording of
the problem
STATE the answer to the problem clearly with
appropriate units.

Solving Problem ExampleSolving Problem Example
The John Hancock Building in Chicago is
1107 ft tall. It has two 342 ft antennas on
top. How far are the tops of the
antennas from the ground?

Solving ProblemSolving Problem
JOHN HANCOCK BUILDINGJOHN HANCOCK BUILDING
FAMILIARIZE: make a drawing
Height of the antenna is 342
ft
Height of building 1107 ft
What is the height of top of
the
antennas from the ground?
h

TRANSLATE:
We translate the problem to the following
addition sentence using the variable h
1107 + 342 = h

SOLVE
To solve the equation, we carry out the
addition sentence:
1107
+342
1449
Therefore, 1449 = h, or h = 1449

CHECK
We check the height of 1449 ft in the original
problem. We can repeat the calculation.
We can also check the reasonableness of
the answer. We would expect our answer
to be larger than either of the heights, which
it is. We can also find an estimated answer
by rounding:
1107 + 342 ~ 1100 + 300 = 1400 = 1449

STATE
The height of the top of the antennas from
the ground is 1449 ft.
