Think I may have gone wrong. 22a ---a musical instrument

and 17d an important part of maths -u---r-

If 17d is numbers, then the musical instrument has to be -b-a !?!
If 22a is tuba then 17d has to be -u-u-r-

can anyone help please ?

I recall numbers is right- it has been answered before

22a: oboe
17d: number

[factor-fiction]

You say ?B?A then suggest TUBA- but that doesn't fit

[spassky]

-b-a ?

Looks like your A is wrong, spassky, if the answer is Oboe.
