Why purchase this book?

  1. Solving a "Numbers" challenge is entertaining.
  2. "Numbers" helps develop the habit of looking at available resources and determining how best to utilize them to advance toward a goal. In "Numbers", those resources are a set of integers. In life, we have time, talent, and various assets (knowledge, money, personal contacts, physical items, etc.). The four basic math functions in "Numbers" have direct analogies in the real world -

    • Addition ⇔ Benefits
    • Subtraction ⇔ Costs
    • Multiplication ⇔ Synergies
    • Division ⇔ Counter-forces (e.g., taxes)

    Because of that, it is easy to transfer concepts from one arena to the other. Fundamentally, we maximize the value from positive synergies, and try to use counter-forces to our advantage, as we work to get the greatest benefit with the least cost.

  3. Where else could you find something that would develop thinking skills, provide entertainment, and have a classy cover, all for the low and unique price of $6.28?
