The comic shows some mathematical equations involving hearts:

Square root of heart = the top half and bottom half of a heart next to each other under a square root sign, and under that another bottom half of a heart that doesn't line up with the top half.

cos heart ≤ 1

d/dx heart = 1

2-by-2 identity matrix heart = heart if heart is a 2 by `n` matrix

F{heart} = 1/sqrt(2π) integral -∞ to ∞ f(t) e to the `i` `t` heart `dt` is the same as

F{`x`} = 1/sqrt(2π) integral -∞ to ∞ f(t) e to the `i` `t` `x` `dt`
