= = = __Equation__ =  An equation is an equality of two expressions which has one or more variables. These are generally represented by letters of the alphabet. Each expression of an equation is called member, that is, an equation has two members. In the members, we can find variables and constants. Both data can be added, subtracted, multiplied or divided. If we want to find the value of the variables, we must perform the necessary mathematical operations. The value of variables can be one, some or none. This depends on the type of equation. Equations can be classified as follows: Now, a monomial and a trinomial are two types of polynomials. Both are equations which can have one or more variables. But, a monomial only has one term while a trinomial has three terms.
