To have difficulty with/in

[Etern1ty]

I was doing some tests and came across next 2 sentences (I copied answers, so it's supposed to be right):
Dipak had difficulties with the archery on the adventure weekend.
Chloe has difficulty in doing her maths homework on her own.

1. What do you usually use? With or In? I though "with" but...
2. Is it wrong to say "has difficulty with doing her maths"?
I'm a bit confused, there must be 2 alternatives, or only one, or what?:)
The only clue I have is to use in with -ing forms...?

With
2. Is it wrong to say "has difficulty with doing her maths"?
No, you can use either. For exam purposes, if in doubt, use 'with'.
You can also say: Chloe has difficulty doing her maths.

The only clue I have is to use in with -ing forms...?
Yes, that sounds reasonable.
Consider these:
1. I'm having trouble studying.
2. I'm having trouble in studying.
3. I'm having trouble with studying.
1 is most common, 3 is also right, but 2 is less likely.
