10 9 8 7 6 5 4 3 2 1 = 2020

(10 + 9) * 8 * (7 + 6) + 5 * (4 + 3 + 2) - 1 = 2020

Yes, of course. The solution was already on that page. There might be an interesting discussion (I think) about how to arrive at answers like these and whether the algorithms might be doable on our machines.

I haven't figured it out, but it looks like a pretty large number of combinations to just use brute force..
