Number and Operations - Rational Numbers: Add, Subtract, Multiply, and Divide
(3) Number and operations. The student applies mathematical process standards to represent addition, subtraction, multiplication, and division while solving problems and justifying solutions. The student is expected to:
(A) recognize that dividing by a rational number and multiplying by its reciprocal result in equivalent values;
(B) determine, with and without computation, whether a quantity is increased or decreased when multiplied by a fraction, including values greater than or less than one;
(C) represent integer operations with concrete models and connect the actions with the models to standardized algorithms;
(D) add, subtract, multiply, and divide integers fluently; and
(E) multiply and divide positive rational numbers fluently.
