About - Easy as 1,2,3 and More

For example, can you make the number 9 by combining 2,4,6 and 8? Sure, it's

9 = (4 + 8 + 6) / 2 or maybe

9 = 8 + (6 - 4) / 2

both are valid solutions. There are 12 different puzzles in all

For each puzzle there will be a PDF file that can be easily printed and posted.
