# Grandpa's crazy math. Another Grandpa Mystery

Grandpa says : " Bit of a stretch but--

2.72 = 1000 x 10000

Is he crazy or genius?

2.72

e = 2.718281828... ~ 2.72

1000 x 10000

M = 1000 and C= 100 in Roman numerals so $$c^2 = 10000$$

Relatively speaking I think Grandpa is a genius

$$E = mc^2$$

• Its all relative, isnt it @Tom?
