Discrete math | How many 7-digit numbers have their digits in increasing order?`

[fathom current]

I'd interpret "7-digit numbers" that as "integers at least 10⁶ and less than 10⁷"

"increasing" is definitely ambiguous between "strictly increasing" or "nondecreasing" though

@viral sonnet usually 0123456 doesn't count

and the order is likely strictly increasing, 11112 don't count

so yeah you got it right

I think it would include, for example, 1234569
