The question says she splits 20 cards into 6 groups so you would add all the numbers together and divide by 6. The total that i added up to was 210 so divide by 6 and you get 35 so each group adds up to 35. I started with 18+17=35 whereas my friend did 20+15=35. My second sum was 20+12+3=35 my friends second sum was 12+8+5+10=35. My next sum was 19+16=35 and her sum was 7+13+9+6=35. My sum next was 14+13+8=35 her sum was 3+17+11+4=35. My sum was 2+1+11+5+7+9=35 and she said 14+1+2+18=35. My last sum was 4+6+10+15=35 and Jessica's was 19+16=35. There was 7 of us and we all got different answers.
