Another Answer: 12*0+1 = 1
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 11 - 9,999,999 = - 9,999,978

Another Answer: 12*0+1 = 1
it equals 62
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 11 - 9,999,999 = - 9,999,978
Any value times 0 is 0 so 0 + 1 = 1
(because zero time 1= 0 plus 1)
Anything multiplied by 0 is 0, so all the ones before the 0 can be ignored. It is now 0+1 which equals 1.
