Strategies

This exercise is easy to get speed badges using basic arithmetic. It is easy to get accuracy badges if one starts to use the calculator to increase speed on problems where it is appropriate.

  1. There are only three problems per set, so users will need to go faster to avoid the downtime during loading and calculation.
  2. Even if uses choose to use a calculator against the spirit of the practice, they shouldn't rely on it. Some problems (those without carrying) are faster to do without a calculator.

Real-life Applications

  1. Addition can be used for adding objects, like adding money totals.
  2. Addition is a major fundamental for higher math levels like algebra, calculus, and more.
