And you probably will too!
Prove to your kids that math can be cool by showing them these tricks:

Think of your age in years
Multiply your age by 2
Add 10
Multiply by 5
Add # of siblings you have
Subtract 50

The digits in your answer will be your age followed by the number of siblings you have.

Think of the first three digits of your phone number (NOT the area code)
Multiply by 80
Add 1
Multiply by 250
Add the last 4 digits of your phone number
Add the last 4 digits of your phone number again.
Subtract 250
Divide number by 2

Your answer should be your phone number.
