Answer 1

Using "number +1" instead of "number" as the upper limit should take care of that.

Answer 2

Thank you I did that and it worked 😊😊😊

Answer 3

Your code works for me. Although there seems to be an issue with sololearn right now where you may have to try running it multiple times because sometimes there is no output.

Answer 4

It says 12*45*7

Answer 5

That's what it's supposed to say, isn't it?

Answer 6

Yes I was asking if that is what it said

Answer 7

No the "7" is missing.

Answer 8

OK

Answer 9
