Evaluating Algebraic Expressions
Read the following instructions in order to complete this discussion, and review the
of how to complete the
math required for this assignment:
Write your birth date or the birth date of someone in your family as mm/dd/yy. (Example: March 13, 1981
is written 3/13/81, and November 7, 1967 is written 11/7/67).
Now let a = the one- or two-digit month number,
b = the
of the one- or two-digit day number, and
c = the two-digit year number.
(Our example: a = 3, b = -13, and c = 81
a = 11, b = -7, and c = 67)
Use the following algebraic expressions for parts 3-5 of the discussion:
(a - b)(a
+ ab + b
(b – c)
(2b – a)
Evaluate the three given expressions using the, b, and c from your birth date.
Make sure that b
when you plug in the values
After you have your math worked out on scratch paper, post your results as well as a description of
the steps you took to evaluate the expressions.
Did you notice anything interesting about the results of a
and (a - b)(a
+ ab + b
)? Was this
coincidence or do you think there is a reason for this?
