The Complex Number System | HSN-CN |
Perform arithmetic operations with complex numbers. | |
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. | |

5. Represent addition, subtraction, multiplication, and conjugation of complex numbers geometrically on the complex plane; use properties of this representation for computation. For example, (–1 + √3 i)³ = 8 because (–1 + √3 i) has modulus 2 and argument 120°. | |

Vector and Matrix Quantities | HSN-VM |
Represent and model with vector quantities. | |
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). | |
CCCs linked to HSN-VM.1 | None |
2. Find the components of a vector by subtracting the coordinates of an initial point from the coordinates of a terminal point. | |
CCCs linked to HSN-VM.2 | None |
3. Solve problems involving velocity and other quantities that can be represented by vectors. | |
CCCs linked to HSN-VM.3 | None |
Perform operations on vectors. | |
4. Add and subtract vectors. | |
a. 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. | |
b. Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum. | |
c. 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, and perform vector subtraction component-wise. | |
CCCs linked to HSN-VM.4 | None |
5. Multiply a vector by a scalar. | |
a. Represent scalar multiplication graphically by scaling vectors and possibly reversing their direction; perform scalar multiplication component-wise, e.g., as c(vx, vy) = (cvx, cvy). | |
b. Compute the magnitude of a scalar multiple cv using \|\|cv\|\| = \|c\|v. Compute the direction of cv knowing that when \|c\|v ≠ 0, the direction of cv is either along v (for c > 0) or against v (for c < 0). | |

Perform operations on matrices and use matrices in applications. | |
6. Use matrices to represent and manipulate data, e.g., to represent payoffs or incidence relationships in a network. | |
CCCs linked to HSN-VM.6 | None |
7. Multiply matrices by scalars to produce new matrices, e.g., as when all of the payoffs in a game are doubled. | |
CCCs linked to HSN-VM.7 | None |
8. Add, subtract, and multiply matrices of appropriate dimensions. | |
CCCs linked to HSN-VM.8 | None |
9. Understand that, unlike multiplication of numbers, matrix multiplication for square matrices is not a commutative operation, but still satisfies the associative and distributive properties. | |
CCCs linked to HSN-VM.9 | None |
10. Understand that the zero and identity matrices play a role in matrix addition and multiplication similar to the role of 0 and 1 in the real numbers. The determinant of a square matrix is nonzero if and only if the matrix has a multiplicative inverse. | |
