I don't get this..
It's like a riddle thinger..
If 9 times 9 is 7 10 times 9 is 9 10 times 8 is 8 8 time 8 is 2 What is 9 times 7 ? It says to "Think mathematically. There is a pattern of calculating involved." Anybody got any idea what this is??? What the answer is??[g)] |

Multiply the numbers (using "normal" multiplication), then take the difference between the digits.
9 * 9 = 81 and 8 - 1 = 7. 10 * 9 = 90 and 9 - 0 = 9. 10 * 8 = 80 and 8 - 0 = 8. 8 * 8 = 64 and 6 - 4 = 2. Since 9 * 7 = 63, the answer you're looking for is probably 6 - 3 = 3. |
