Hi,

can someone help me with understanding this:

Let 𝑨 = {𝒏 ∈ ℤ|1 ≤ 𝒏 ≤ 𝟏0}.

For any positive integer 𝒎 we define the set 𝑨𝒎 by𝐴𝑚 = {𝑛 ∈ 𝐴|𝑛 𝑖𝑠 factor of 𝑚}

So I created set A = {-infinite,...,-1,0,1,2,...,10}

But I'm stuck with Am.

Is this right solution?

A1 = {1}

A2 = {1,2}

A3 = {1,2,3}

...

?

Thanks
