Question 1
We can write 8 as a product of natural numbers whose sum is also 8. For example, $8=1\times1\times2\times4$ and $8=1+1+2+4$. How many ways can we write 12 as a product of natural numbers whose sum is also 12?
Practice convention: use at least two positive integer factors. Changing their order does not give a new way.
