Greetings!

Assuming you're using the bash shell, try this;

while true
do
if [ $i -le 10 ]; then
echo "$n * $i = 'expr $i \* $n'"
i='expr $i + 1'
fi
done

If that doesn't work, I would re-read that chapter in your classbook.
:)

thanks for your respond but that you wrote get inside the infinite loop wants

-le: unary operator expected

ı should check it my slayts one more time

Hint: Between the lines, that error is telling you that the variable you are comparing in your test, is not an integer. So, investigate how $i is getting set, i.e. is it getting set to a string value by accident or by logic error (or perhaps it is empty when the loop begins?)?

I left out a "then if i = 10...break" intentionally. We get quite a few "homework questions" here, and I wasn't sure if that's what your post was. :)
