Pick any number. Multiply by 6. Add 13. Subtract 7. Divide 3. Divide 2. Then subtract by the original number you chose. Your result will always be 1. Tell a friend to mentaly multiply their age by 2. Tell them to add 14 then divide 2. Ask your friend what number they currently have. Now, you mentally subtract 7 from the number they tell you, then you'll know your friend's age.
The number is 21. 21 ÷ 3 = 7 7 - 3 = 4
The number is 72 because (72/9)-7 = 1
Nope... to check if a number will divide by 3 - add the digits of the number together. In this case, 6+7+7=20, which will not divide exactly by three.
