### AR.Math.Content.HSN.RN: The Real Number System

#### AR.Math.Content.HSN.RN.B: Use properties of rational and irrational numbers

AR.Math.Content.HSN.RN.B.4: Simplify radical expressions. Perform operations (add, subtract, multiply, and divide) with radical expressions. Rationalize denominators and/or numerators.

### AR.Math.Content.HSN.CN: The Complex Number System

#### AR.Math.Content.HSN.CN.A: Perform arithmetic operations with complex numbers

AR.Math.Content.HSN.CN.A.1: Know there is a complex number i such that i² = -1, and every complex number has the form a + bi with a and b real.

AR.Math.Content.HSN.CN.A.3: Find the conjugate of a complex number. Use conjugates to find quotients of complex numbers. Use conjugates to find moduli.

#### AR.Math.Content.HSN.CN.B: Represent complex numbers and their operations on the complex plane

AR.Math.Content.HSN.CN.B.4: Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers). Explain why the rectangular and polar forms of a given complex number represent the same number.

AR.Math.Content.HSN.CN.B.5: Represent addition, subtraction, multiplication, and conjugation of complex numbers geometrically on the complex plane; use properties of geometrical representation for computation.

#### AR.Math.Content.HSN.CN.C: Use complex numbers in polynomial identities and equations

AR.Math.Content.HSN.CN.C.7: Solve quadratic equations with real coefficients that have real or complex solutions.

### AR.Math.Content.HSN.VM: Vector and Matrix Quantities

#### AR.Math.Content.HSN.VM.A: Represent and model with vector quantities

AR.Math.Content.HSN.VM.A.1: Recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes (e.g., v, |v|, ||v||, v).

AR.Math.Content.HSN.VM.A.2: Find the components of a vector by subtracting the coordinates of an initial point from the coordinates of a terminal point.

AR.Math.Content.HSN.VM.A.3: Solve problems involving velocity and other quantities that can be represented by vectors.

#### AR.Math.Content.HSN.VM.B: Perform operations on vectors

AR.Math.Content.HSN.VM.B.4: Add and subtract vectors. Add vectors end-to-end, component-wise, and by the parallelogram rule. Understand that the magnitude of a sum of two vectors is typically not the sum of the magnitudes. Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum. Understand vector subtraction v - w as v + (-w), where -w is the additive inverse of w, with the same magnitude as w and pointing in the opposite direction. Represent vector subtraction graphically by connecting the tips in the appropriate order. Perform vector subtraction component-wise.
