Scenario
We need a subscript for our formula.
Approach
Copy one of the below numbers, letters, or operators and paste in where the subscript is needed (If you need other operators search for operator subscript unicode character
):
₊ ₋
₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉
ₐ ᵦ 𝒸 𝒹 ₑ 𝒻 𝓰 ₕ ᵢ ⱼ ₖ ₗ ₘ ₙ ₒ ₚ ᵩ ᵣ ₛ ₜ ᵤ ᵥ 𝓌 ₓ ᵧ 𝓏
For example for S sub e
do this:
Sₑ
Bonus
For superscripts use ^. So for 1². First type 1 then ^ then 2. The ^ is located on the 6 on my keyboard.
