Soooo easy, Ilan... ?
YEAR=2020 --> YE=20 and AR=20
YETI = 2020 (the last time it was seen, just yesterday, dancing in my garden) (*)
So, TI= (YE)(TI) - (YE) =20
Also, we have the known resut
YE-YE = (20)(20) = 2020, that will make this year so good!!
On the other hand, if we take the price of a miso soup tin at the supermarket, we have that
TIN = 209, but TIN = (TI)N = (20)N = 20N , so N= 9
Joining all the results, YEN = 209, the same year that Matshuhito emperor decided to have breakfast later than usual, saving his life and his country from being invaded by the enemy. With this, we close the circle, that is the real meaning of YEN (circle, round)
(*) I know it's hard to believe, but luckily I could take some pics ?
