The other name for Variants is 'Deviants'
- avoid them or you'll suffer

Because that is the new and trendy way of declaring variables

You'll find a lot of canny coders still do that
- even in (the better) examples from MS

Because there is a Default Type for VB
- it is historical
- absurdly the default has migrated over the years from Single, Double
to Deviant

Stick: DefObj A-Z at the top of /all/ your code and it will save you
many visits to a tricologist.

If this is homework, then your teacher is better than most.

Normally I don't do homework (unless I do)

However the real answer to the underlying questions is that the very
first BASIC came from Dartmouth and had two types of variables

A$ - this is a string
A - this is some sort of a number

Later 'street BASICS' mostly written by Microsoft, invented different
types of numbers % ! # & @ in that sequence

When they ran out of funny characters to stick at the end of a 'name'
they started denigrating the idea of 'suffix designation'

A bit daft
- as they could not see the difference between the wood and the nails
