Doesn’t the step say to use I++?

As the hint suggests, type(( I++ )) excluding the $ and see if something happens.

I took another screenshot where you can see what the step says.
and try entering (( I++ )) , but it still returns an error.

Looks like you are making some minor syntax-related mistakes. It’s OK, bash expressions can be confusing. Note that expressions are sensitive to spaces.

For this particular challenge, there are some hints:

HINTS

• If it didn’t print 11 for I, enter I=11 to set it to 11
• Type $(( I + 4 )) in the terminal and press enter

First set the value for I like this: I=11.
Then, type $(( I + 4 )) [spaces included] and see the results.
