How many ways can you make 175?

Answer 1

Infinitely many.

Start with addition:

87+88, 86+89, 85+90, ... 1+174, 0+175, -1+176, -2+177, ...

Netx, add 1 decimal digit

87.4+87.6, 87.3+87.7,

and then 2 decimal digits and so on.

Next, add irrationals.

And that is just addition of two numbers. Next, try adition of 3 numbers, then of 4 numbers, etc.

And then start on multiplication.

And then there are other binary operators.
