Human Algebra

In the following equations, let
b = boy, g = girl, m = mother,
f = father, s = son, d = daughter.

b + g = a date
(b + g) + m = a chaperoned date
(b₁ + g₁) + (b₂ + g₂) = a double date
(bg) = marriage
m + f + s + d = a family
m + (d + s) + f = a protective family
(g₁ + g₂) = twin daughters
b₁ <> b₂ = son having an identity crisis
d + D = daughter walking her Great Dane
f + @&%#$ = father hit his thumb with a hammer
m + d + s = single parent family
m + f + d + s = family with a stepdad
m^b = mother expecting a new baby boy
