n_x

# alive at year=x
l_x
- Proportion surviving in relation to n₀
- n₁/n₀
- n₂/n₀
d_x
- # dying between 2 intervals
- d₀=n₀-n₁
- d₁=n₁-n₂
q_x
- Rate or mortality
- q₁=d₁/n₁
- q₂=d₂/n₂
T_x

Diagonal summation on L_{x and previous}T_x
e_x
- e_x=T_x/n_x
- e₀=T₀/n₀
L_x
- Average between 2 points
- L_x=(n_x+n_x)/2
- L₈=(n₉+n₈)/2
- L₇=(n₈+n₇)/2
