Friday a student, Miss P, showed our 2nd period class how to take a number and always get 5 as the answer. By 5th period, we were testing it with any number we could think of.
Here is the formula: number + (number +1) +9 divided by 2 - original number.
STEPS:
Choose a number.
Add number you chose to the next number when counting.
Add 9 to that sum.
Divide that sum by 2.
Subtract the original number from that quotient.
You should have a difference of 5!!!!
Example: 8+9=17+9=26/2=13-8=5
I challenge you to tell me why this always equals 5. (Hint.. look at just the numbers in the formula)
Enjoy!
