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 x=7x.
By adding 3xy+2xy, we get xy=5xy.
By adding as and bx, we get ax+bx=x.
Remember:
Monomials can be added only if they have the same variables with identical powers.
