Before you open the lunch menu or order that cheeseburger or consider eating the cake with the frosting intact, haul out the psychic calculator and start tinkering with the budget.

I love math and was a math teacher for many years, so it was fun for me to write several math books, including 'Fraction Fun,' 'Calculator Riddles,' and 'Shape Up!' 'Fun with Triangles and Other Polygons.'
