Symbols are a concise way of giving lengthy instructions related to numbers and logic.
They are an invention, not a discovery. They are a communication tool. They are used to eliminate the need to write long, plain language instructions to describe calculations and other processes.
For example, a single sign stands for the entire process for addition. The familiar plus sign eliminates the need for a long written explanation of what addition means and how to accomplish it.The word subtraction or minus is replaced by sign - . The word multiplication or product is replaced by its sign 'X'. The word division is replaced by its sign as ÷ Signs are 'pictures' or 'abstract figures' that represent and connect concrete mathematical concepts. Drawings of 2-D and 3-D shapes, such as circles and spheres, are one kind of symbol. However, the term is most often used with the markings that tell students whether to add, subtract, multiply or divide; they also indicate which functions need to be done first.
Once students learn a concept, you may find that teaching the related sign is relatively easy because it's simply a matter of adding a new sign to their toolbox. In other words, the hard part for most kids is understanding how to multiply, rather than understanding that the sign x represents multiplication.
