10 + 10 + 10 + 5 + 5 +1 = 41.
3/10 + 7/10= 1
You have 10 "pairs" of numbers which all give the answer, -1 (negative one or minus one). So your sum is -1 + (-1) + (-1) +... Ten times. i.e (-1) multiplied by 10. So the answer is -10 (negative 10).
(10 + 1) x 10/2
300000000+9000000+200000+70000+30+1 =309270031 All the addition can happen in the same step. When all the operations are the same it can be done that way.
25+10+10+10+1+1= 57
