新gre数学重要考点：Multiplying Monomials
Multiplying Monomials
To multiply two monomials, multiply the coefficients and add the power of the variables.
By multiplying 3x and 4x, we get (4*3)x∧(1+1)=12x2.
By multiply 3x and 4y, we get (4*3)xy=12xy.
Remember:
Do not forget to add the powers of the same variable.
The terms need not be like terms to be multiplied.
