Let's take the Type 94 as the example, starting from 0 to +5, it'll cost you one Development Material and one Screw to upgrade it once (Assuming you're not paying extra), so that's a total of 6 of each to reach +6.

At +6 to +9, it'll cost you two Development Materials, one Screw and one Type 94s per attempt, you'll probably start seeing fails around here.

For the final upgrade at +10, you'll need three Development Materials, three Screws and two Type 94s per attempt, cross your fingers for this one.

Let me know if it's still not clear.
