When working with decimals using a calculator, you can enter and treat them just like integers; the same rules of addition, subtraction, mul... |

# Angle relationships between intersecting lines and parallel lines example
We are given that the angle EDG is equal to α.
Angles that lie on the same side of a straight line, are always supplementary and their sum is equal to 180°. Therefore, the angles EDG and CDE are supplementary and EDG+ CDE=180°.
The angle CDE=1... |

Tweaking a proof of the infinitude of primes
This blog presents two proofs of the infinitude of primes. The first one is the standard proof that is due to Euclid (around 300 BC). The second one is due to Christian Goldbach (from a letter to Leonhard Euler in 1730). This post attempts to generalize the second one. The ... |
