I want to know the answer to the following question:
What number was the Tironian note visually similar to?
All the background I'm provided with is that "The Latin alphabet of the time still lacked the letters ⟨j⟩ and ⟨w⟩, and there was no ⟨v⟩ as distinct from ⟨u⟩; moreover native Old English spellings did not use ⟨k⟩, ⟨q⟩ or ⟨z⟩.". Is that enough to answer the question?
