The first part will consist of several multiplications involving one-digit multipliers. Because of the need for urgent action, the greatest challenge is to move rapidly to much increased energy efficiency and to non-fossil-fuel energy sources. In mathematical terms, the exponent for the radix (base) of 10 increases by 1 (to the left) or decreases by 1 (to the right). These subtractions are what you always end up with AFTER you regroup to subtract.

Since the monitorial method promised to teach large numbers of pupils basic literacy and numeracy skills, it gained the support of those who wanted to provide basic elementary education at limited costs. As in the trick problems given earlier, sometimes our "understanding" simply gets a kind of blind spot or a focus in a different direction that blocks a particular piece of knowledge. See how quickly you can label the countries around the world.
