MA.9-12.N-RN.B.3 - [Standard] - Explain why the sum or product of two rational numbers is rational; 
that the SUM of a RATIONAL number and an IRRATIONAL numberis IRRATIONAL
and that the PRODUCT of a nonzero rational number and an IRRATIONAL number is IRRATIONAL
Which expression could represent a Rational number?

  Both -a and -b
  -b
Let 'a' represent a non-zero rational numberand let 'b' represent an irrational number
Which expression could represent a Rational number?
Let 'a' represent a non-zero rational numberand let 'b' represent an irrational number
  a + b
  a + a
  b + b
Let 'a' represent a non-zero rational numberand let 'b' represent an irrational number
Which expression could NOT
represent a Rational number?
