The constant is also known as Archimedes Constant‚ although this name is rather uncommon in modern‚ western‚ English-speaking contexts. Many formulae from mathematics‚ science‚ and engineering involve π‚ which is one of the most important mathematical and physical constants.[5] π is an irrational number‚ which means that its value cannot be expressed exactly as a fraction m/n‚ where m and n are integers. Consequently‚ its

Mechanical Engineering History of Mechanical Engineering Engineering in one form or another is among the oldest of professions. The Egyptian pyramids are examples of ancient engineering feats and many of the bridges‚ roads and aqueducts constructed by the ancient Romans are still use today. Engineers were originally simply builders who worked with stone and other basic materials. They were either self-taught or learned their craft from more experienced workers. The military operations

Part 1. Describe the order of operations and explain how it is used to simplify expressions. Explain specifically the order in which mathematical operations must be performed to correctly simplify an expression. The order of operations is a rule that always applies to mathematical problems. It includes addition‚ subtraction‚ multiplication and division as well as grouping of numbers (such as in parentheses and powers). It gives a definite order of how to do a problem involving multiple operations
