  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.

  有一部分考生认为新GRE数学具有一定的难度,这其中的原因是由于考生在复习时没有把新GRE数学的基础打牢。想要新GRE数学考好,复习的时候一定要把基本概念和重要考点都弄扎实。祝大家都能取得理想成绩!
