Question

when you split 9 or square it, it will become 3 times 3. when you split ten into two seperate multiples of it, it equals 5 times 2. When you times the 3 times the 2 and the 5, it will equal 15 and 6. When you add them it equals 21. How is this possible? 9+10 =21.

Answer 1

9+10 equals 19 not 21.

7 x 3 = 21

10+11=21
