This research aims to describe the number formation strategy as an application form of the Pythagorean theorem. A number formation strategy to simplify calculations on the application of the Pythagorean theorem is needed since many mathematical problems solving involve Pythagorean theorem. In some mathematical problems, the Pythagorean theorem is only used as a tool to answer the real problem, for example is a problem in Geometric. This research applies a literature review method. There are three steps should be met to use the number formation strategy in this paper, namely: (1) ensuring that the two side lengths of a right triangle have the same factor, (2) changing integers other than the same factor (if it is the same, select one) becomes the root number, and (3) determining the side in question, if what is being asked is the longest side (hypothenuse) then the two numbers in the same root (radicand) must be added, otherwise if what is being asked is not the hypotenuse (not the longest side), then the two radicans must be subtracted while still being positive.

It is sometimes argued in support of discounting future costs and benefits that if we gave the same weight to the future as to the present, we would invest nearly all our income, but never spend it. Rather than enjoying the fruits of our investments, we would always do better to reinvest them. Undiscounted utilitarianism (UU), so the argument goes, is collectively self-defeating. This attempted reductio ad absurdum fails. Regardless of whether each generation successfully followed UU, or merely attempted to follow it, we could never get trapped in endless saving. The real problem is different: without the ability to foresee the end of the world, UU cannot tell us how much to save. Discounting is a defensible response, but only when coupled with a rule against risking catastrophe.

The real problem for children of poverty may not be weak academic skills, poor teachers, or scant resources, but a lack of hope that they can alter their life conditions through effort.
