What are Expressions?
In mathematics, an expression or mathematical expressions are a combination of symbols, variables, numbers, operations, brackets, functions, and grouping to help determine the order of operations.
It is said that at the end of the 16th century Francois Viete introduced symbols. These symbols are now called variables today, they are used for representing unknown numbers. This has created a new algebra that consists of computing with symbolic expressions as if they were numbers.
It is also said that in the 17th century the use of "x" was used in representing unknown variables and, It is said that it was Rene Descartes who was responsible for this development. It's being thought that this was first used in the published form of "La Géométrie"
There are many things you can do with expressions such as: simplifying, expanding, evaluating, and many more...
Expressions can be used in the real world to solve scientific problems, doing carpentry, and even in architectural activities/jobs.
In this blog, there is a page containing information on how to solve expressions such as: simplifying and expanding them. What is simplifying and expanding you asked??
Expanding and simplifying expressions is the action of multiplying out the brackets from an expression and then simplifying the resulting expression by collecting the like terms available, there are several types of expanding and simplifying questions which comes with different method in solving them...If you want to learn these methods feel free to check out our pages titled:
