The last time it happened was on July 14, 1998.
It will happen for the first time in the
new millennium on January 1, 2001; again on
January 2, 2002; and yet again on
February 1, 2002.
What is
"it" and what are the
two dates left in this century on which
"it" occurs?
Solution:
Rewriting the dates with slashes, the MULTIPLICATION
DAYS form a multiplication equation.
| 7/14/98
|
==>
|
7 x 14 = 98
|
| 1/1/01
|
==>
|
1 x 1 = 1
|
| 1/2/02
|
==>
|
1 x 2 = 2
|
| 2/1/02
|
==>
|
2 x 1 = 2
|
So the last two dates in this century are:
| 9/11/99
|
==>
|
9 x 11 = 99
|
| 11/9/99
|
==>
|
11 x 9 = 99
