Vector Operations

★★☆☆☆Middle School

📖Definition

Basic operations on vectors: addition, subtraction, scalar multiplication.

\vecu + \vecv = \beginpmatrix u₁ + v₁ \\ u₂ + v₂ \endpmatrix

Vector addition (component-wise)

c\vecv = \beginpmatrix cv₁ \\ cv₂ \endpmatrix

Scalar multiplication

\vecu - \vecv = \vecu + (-1)\vecv

Vector subtraction

예제 1★☆☆☆☆

If u = (1, 2) and v = (3, 4), find u + v.

예제 2★☆☆☆☆

If v = (2, -3), find 3v.
