## Quick Answer

Perform vector algebra operations in 2D or 3D space. Enter vector coordinates to calculate addition, subtraction, dot product, cross product, and magnitude.

## Definition

A vector calculator is a linear algebra tool that performs mathematical operations on vectors in two-dimensional or three-dimensional Cartesian coordinate space. The calculator supports operations including vector addition, subtraction, scalar multiplication, dot product, cross product, magnitude computation, and angle determination. It applies vector arithmetic formulas, such as multiplying corresponding elements and summing them for dot products, to ensure perfect precision. Physics and engineering students use this utility to analyze forces and spatial rotations.

## How to Use

1. **Select space dimension** — Choose whether you are working with two-dimensional or three-dimensional vectors.
2. **Input vector coordinates** — Type the components of vectors A and B in the coordinate input fields.
3. **Read operation results** — View the sum, difference, dot product, cross product, and magnitude calculations.
