Yes, sir.

You may use any mathematical symbol(s) that you wish, but you must ensure that each digit from 1 to 9 is used once and only once.

Well done.

Note that this is not the particular solution that I was looking for, but it certainly satisfies the initial conditions. So, I'll leave this problem open if anyone wishes to come up with another solution.

Excellent!

However, there is still at least one more solution. 🙂
