Using all the digits from 1 to 9 ONCE ONLY?

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.

((9-8)+(7-4)-(3-1)-(6-5))/2 =

(1+3-2-1)/2 =

1/2

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.

1/2-3-4+5-6+7-8+9
(12-34.5+67)/89

Excellent!

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