I had to read twice to see the ##\hat\imath##.
Perhaps you are working with a computer ? Or did your teacher mark tha answers as wrong :rolleyes: ? Probably not.

Perhaps the program wants a space between the 2 and the dimension (as in the template --- --) ?

The teacher told me that I should ignore positive signs in my answers then they would be correct. Thank you for your interest in helping me!
