When trying to do use it with my son, I was having trouble finding Vectorize (need tooltips)

But I realise that

- I never use matrix maths, havn't in years, can't even remember when I last did.
- I always use vectors, or more accurately columns of data, every time I use matlab or want to use SMath
- I very rarely use arrays, except as a table of columns of data (vectors)

I cannot explain (credibly) to my son , why formulas don't work, unless he puts the magic vectorize operator over every single formula.

For me, and my kids, it would be much more logical, efficient, and intuitive if the whole sheet could be globally vectorized.
For us there would be exactly zero drawback if this was the default behaviour, or if a user could make it the default for new sheets.
