Heh, perhaps we should petition to have a new computer key and symbol added to the world's way of writing maths, something like maybe a downward angled slash to mean prefix (-)
Such a symbol already exists, but isn't in the ASCII set: (-) (unicode 0x2D) "hyphen minus" and (‐) (unicode 0x2010) "hyphen" are not the same as (−) (unicode 0x2200) "minus sign" notably also, not the same as ‒, –, — and ― (figure dash, en- dash, em-dash and horizontal bar). Bob
