Internet Math Challenge
Deadline for solutions: Friday, 14 November 2003
The addition problem below looks wrong, but
it's actually correct. The secret is that each alphabet
letter actually stands for a digit. The letter O does not
necessarily represent the number zero, but we will insist
that the leading digit in a multi-digit number should not be zero. (So
neither T, F, nor E can be zero.) Discover which letters represent
which digits to make the addition correct.
There are actually four
correct answers. You need only find one of them,
but if you want an extra challenge, try to find them all!
