THIS IS NOT ANOTHER MATH WORKBOOK.
The Math Detective Agency is a secret math adventure book for kids ages 9–12 — part spy thriller, part brain challenge, and part math enrichment experience unlike anything in your child's classroom.
Your child is recruited by Professor Zero, director of CIPHER — an underground agency protecting the world's greatest mathematical secrets. The Codex has been stolen by the mysterious General Minus. Only young recruits with sharp minds can recover it.
20 missions. 20 hidden locations. One enemy who never makes mistakes.
Every mission unlocks a new mathematical superpower: mental math shortcuts, secret codes, number tricks, hidden patterns in nature, and famous number mysteries mathematicians still talk about today. The kind of math most schools never teach.
