Critique: VM simplifies computation

• This may be indeed be true...

• The approach is similar to that taken by other “speed math” systems (Trachtenberg, Meyers), taking advantage of patterns

• Works well in certain situations, e.g.

• • Subtraction from a power of 10
  • Product of numbers near the same power of 10
  • Product of 2-digit numbers with same first digit and second digits that sum to 10
