I need help on a sum? >.<

Well, considering that maths isn't my strong point, and that I'm under 13...
I can't quite figure out this sum, anyone got any tips?

The following sum needs one + sign and two - sign to be inserted to make it correct.
Put in the three signs:

1 2 3 + 4 5 6 7 8 9 10 = 22

Note: don't give the answer!

Much thanks~

I'm not sure how best to give hints on this, since I found the answer just by trying stuff until I got it, but I'll give it a go.

I don't think I can say much more without outright giving it away.
The hints get progressively more explicit, so go as far as you need to.

Why did the vector cross the road?
It wanted to be normal.

I'm sure it'll push me a little further to solving it. xD
