“WOW! What a cool resource! Full of information and pleasing to the eye! There is so much here, fun facts like the 1980’s creation of Sudoku puzzles, to math symbols of early history from around the world. We also see the pioneers of math, where and who came up with the math formulas we use today in engineering, math and science. Early machines that helped with math calculations to machines that aided in everyday life. My family has loved all the other Big Books and this one is no exception!” — Shannon
