[On Tuesday we offered funny jokes for elementary kids about =
money.  Today’s blog has FOUR slightly tougher use-your-brain =
questions for the kids OR the older crowd. Answers next month. Er, =
tomorrow.]

1. Using only addition, how can you add eight 8’s to =
get the number 1,000?

 

2. What is the smallest three-digit palindrome divisible by 18?  =

class?

 

3. Jake weighs half as much as Joe, and John weighs three times as =
much as Jake. Together, they weigh 720 pounds. How much does each man =
weigh?

 

4. January 1, 2002 was the first "sum-day" of the new =
century (when you write out that date in standard abbreviation, it =
becomes 01/01/02, or shortened further to 1 + 1 =3D 2.  A sum-day =
is a date in which the day and month add up to the year, so today =
(February 28th, 2019) would be 2 + 28 =3D 19 (year) so =
it’s obviously NOT a sum day.

What will be the last sum-day of the 21st =
century?
