They add up to 39
6 + 13 + 2 + 12 + 7 + 14 = 54
13/13 + 12/14 = 13/7 or 16/7
-1 + 13 = 12
13 and 5/8 plus 7/8 = 13 and 12/8, or 14 and 1/2
Plus 12 plus -13 plus plus 1 can be rewritten in mathematical terms as: 12+(-13)+1 or 12-13+1 12-13+1 =-1+1 =0
2(1+2+3+4+5+6+7+8+9+10+11+12+13+14) is the same as the question of the next part is supposed to be 14 plus 14. the answer is simply 1+2 and so on until 14, and then multiply by 2. The answer is 210.
14 + 13 + 9 = 36
13 + 14 = 27
14*13=182
13 and 12/8 = 14 and 1/2
17 + 13 + 12 + 12 + 6 + 9 = 69.
14 + 5 + 13 + 4 + 9 = 45
