Long description for Formula-1

l0 = 100,000

dx = (lx)(lqx),     x = 1, 2, 3, ...

lx = (lx-1)(l - lqx-1),     x = 1, 2, 3, ...

L0 = l0 - (1f0)(d0)

Lx = lx - (.5)(dx),     x = 1, 2, 3, ...

Tx = Lx + Lx+1 + Lx+2 +... + L148,     x = 0, 1, 2, 3, ...

life expectancy = Tx / lx,     x = 0, 1, 2, 3, ...
