Examples

y = 0

y = 0 T1 FORMULA 0 5 y = 0
m > 1

m > 1 T1 FORMULA 0 5 m > 1
O(√N)

O(√N) T1 FORMULA 0 5 O(√N)
p < 0.0001

p < 0.0001 T1 FORMULA 0 10 p < 0.0001
F₁ = 76.59

F1 = 76.59 T1 FORMULA 0 10 F1 = 76.59

Further details

Note that expressions with natural language (as opposed to mathematical) syntax such as the value of F₁ is 90 are not annotated as formula even if their meaning is identical to that of some similar formula (e.g. F₁ = 90).
