POLYNOMIALS

1. Algebraic expression
   Two or more algebraic terms connected by positive(+) or negative(-) signs is said to
   be an algebraic expression.

Eg. : 2x + 3y

4y - 5z

x + 4y - 9z

Having explained the relative terminologies such as constant, variable and algebraic

term earlier, the idea of algebraic expression can be taught to the child without much

difficulty.

2. Monomial
   An algebraic expression having only one term is said to be a monomial.

Eg. : 2x, -4y, 5xy, -9xyz are all monomials as they contain only a single algebraic

term. Note that eventhough the terms 5xy and -9xyz involve more than one

variable they are monomials only.

The concept can be explained to the child with necessary illustrations in Braille.

3. Binomial
   An algebraic expression with two terms is said to be a binomial.

Eg. : x - y, 2y + 4z, 5xy - 7 yz are all binomials as they contain two algebraic terms.
