Understanding Altitude Changes in Flight

The video tutorial explains how to calculate the new altitude of a plane after it descends and ascends. Initially, the plane is at 35,000 feet and descends 2,500 feet. It then ascends six times the descent amount. The tutorial walks through the calculation process, resulting in a new altitude of 47,500 feet. Additionally, it introduces a variable 'd' to represent the descent and forms an expression for the new altitude in terms of 'd'. The tutorial emphasizes understanding the order of operations and combining like terms in algebraic expressions.
