    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.
