Short and Simple
                10 candles stand burning in a dining room. A strong breeze blows in through an open window and extinguishes 3 of them. Assuming the wind doesn't extinguish any more candles, how many candles do you have left in the end?
What is 3?
The 7 candles that manage to stay lit will melt down completely. The only candles that remain in the end are the 3 that are extinguished by the wind and therefore stay intact.
How can you add eight 8's to get the number 1,000? (only use addition)
What is 888 + 88 + 8 + 8 + 8 = 1,000 ?
