Arithmetic is
Greek for “art and skill with numbers.”
Math is
Greek for "method." Humans practice
their
Arithmetic
skills
using
Math methods. Traditionally, we manipulate numbers and
symbols with pencil and paper using
techniques that are hundreds of years
old. Yet surprisingly, in an age of
advanced mathematics, the most common
math mistakes, even for professionals,
