    Students must use their knowledge from fifth grade where students fluently added and subtracted positive rational numbers and from sixth grade where students multiplied and divided positive rational numbers to use all four operations with rational numbers including negative rational numbers. Rational numbers the set of numbers that can be expressed as a fraction, where a and b are integers and b ≠ 0, which includes the subsets of integers, whole numbers, and natural numbers (–6, 0, 8, etc.).
