IT'S SUPER BOWL SUNDAY - bet you didn't know that!

So it's Super Bowl XLV (why do we use roman numerals but we don't use metric).

So it's (X=10, L=50, V=5 so is it 65, NO, X before L means* a minus (who knows why), so 50-10= 40; then V following L means to add 5 (must be new math), so we have 40 + 5 = 45)  Super Bowl 45.  Wouldn't it be simply to say that vs Super Bowl XLV. 

Anyway welcome to Super Bowl 45 Sunday.  Remember we are having a small pre-game party at TYF.

*Subtractive Principle:

Any numeral is counted positively unless there's a larger numeral anywhere to its right, in which case it is counted negatively.  However, proper Roman numbers are subject to the following restrictions about the applicability of the subtractive principle.
The use of the subtractive principle has always been optional. Its systematic use is fairly modern.  For example, it's acceptable to use IIII instead of IV, as is usually done on clockfaces (to "balance" their left and right halves, so we're told).
