Here we will see how to do Algebra 1. When we say that the area of a Rectangle is l * b, these ‘l’ & ‘b’ are nothing but variables which can be assigned different values depending on the dimensions of the rectangle for which we have to find the area. Thus l * b is the generalized formula to find the area of a rectangle which means that we have to find the product of the measures of the length & breadth of the given rectangle.

The fixed & variable values in algebra are brought together by the operations of =, -, * & /. When these values are joined with * or /, we get the terms & these terms in turn, are joined with the help of ‘=’ & ‘- ‘ symbols.

Such relation of terms gives us algebraic expressions. Depending on the number of terms, the expressions are called monomial if they have only 1 term; as 2x, 45, 6a, etc. are monomials. Binomials have 2 terms as 3v + t, 5y - 8, 6 + 2 / 3a are binomials. If the number of terms is 3 then they are called trinomials like 4 - 5x + y is a trinomial and we can generalize them as Polynomials. This is all about algebra 1.
