  Adding Monomials

  To add two monomials of the same variables just add the coefficients.

  Only two like monomials can be added together.

  Example:

  By adding 3x and 4x, we get (3+4)x=7x.

  By adding 3xy+2xy, we get (3+2)xy=5xy.

  By adding as and bx, we get ax+bx=(a+b)x.

  Remember:

  Monomials can be added only if they have the same variables with identical
powers.
