If you needed to quickly add 1+2+3+4+5+6+7+8+9 in your head how would you do it? No calculators and no need to Google any math tricks or the best way to do it or anything like that. Just curious how others think!

I think Gauss had it right. =(1+9) + (2+8) + (3+7) + (4+6) + 5 = 10 + 10 + 10 + 10 + 5 = 45
