That is ridiculous! But I suppose Albert is right, that it is technically correct. But it is still ridiculous.

This was an unintended loss of going from 'E' notation to 'x10^x'.

In my mind scientific notation is a 'number', rather than expression. Like -2 is a number. Or 2+3i.

Maybe they should have written it as 2(10)³.

But then we'll be back to all the arguing about factors/products/BODMAS.

Or just go back to E.
