Post a mathematical riddle.
- Come up with an algorithm that counts down from a number but does not employ the use of a minus sign or any form of subtraction. There are several solutions to this problem.
- How can you add eight 8's to get the number 1,000? (only use addition)
(TQU: 888+88+8+8+8 = 1,000)
- Start with six vertical lines. Then add 5 more lines to make nine.
- Find the pattern: 8, 11, 15, 5, 4, 19, 7, 6, 3, 22, 2
