Time for MATH MINUTE! (provide your favorite theme
music here).
Get
out your paper & pencil because I have a new puzzle for you!!
PUZZLE #9 Birthdate mystery Nov. 6 -Nov. 10
I have a friend who can
guess your birthday month
and day by having you compute a
special number for her
(without letting her see the
details). She then asks you for
the number, thinks for a bit
and tells you your birthday
month and day.
How does she do it?
Here is the number calculation:
Take the month number of your
birthday
(Jan. = 1, Feb. = 2, and so on
) and multiply it
by 5, then add 7 and multiply
that total by 4.
Now add 13 and multiply the new
total by 5.
Last add the day of the month of
your birthday
to this total.
Send your
comments, ideas and solutions before Monday Nov. 13 to
this email address, and in the subject line be sure to
put: < MM >.
