Insert + – x or ÷ each time you see Insert + – x or ÷ each time you see ?, so the results of both the 4-number and 7-number calculations are 12 when working one step at a time from left to right (and no brackets allowed): 2 ? 4 ? 6 ? 8 = 12 1 ? 2 ? 3 ? 4 ? 5 ? 6 ? 7 = 12 Answer: first one : 2-4+6+8=12 second one: 1+2*3-4*5-6-7=12 OR 1+2-3+4-5+6+7=12 There are other possible solutions too.
