Answer:
assuming only positive integers, the answer is 1
Step-by-step explanation:
the smallest number that you can get by adding is:
- start with 0
- then add 1 = 1
- add another 1 = 2
- add another 1 = 3
- add another 1 = 4
- add another 1 = 5
but you can also multiply, and anything multiplied by 0 is 0:
- start with 0
- multiply by 2 = 0
- multiply by 2 = 0
- multiply by 2 = 0
- multiply by 2 = 0
- multiply by 2 = 0
The question does not say that we need to do any specific calculation, it only gives us 2 options and we can choose them as many times as we want.
