Glad to hear that.
Feel free to ask again if you are stuck.

I don’t understand your question.
The problems ask you to show that w=uv Cauchy, given that u, v are respectively Cauchy (which means that it is a given assumption that “u” is Cauchy and “v” is Cauchy).
And what I have done is using the assumptions “u” is Cauchy and “v” is Cauchy, to show what the question wants me to show, that is, their product uv as a new sequence, is still Cauchy.
Still any questions?
The product of u and v is w. That’s the definition given by the problem.
