AI explanation

Formula

Add/subtract corresponding components; magnitude = √(sum of squared components)

Worked example

(1,2,3) + (4,5,6)

Worked example: (1,2,3) + (4,5,6)

Result vector5, 7, 9
Magnitude12.4499

Assumptions

  • Both vectors must have the same number of components.

Frequently asked questions

How do you add vectors?

Add each pair of corresponding components — (1,2,3) + (4,5,6) = (1+4, 2+5, 3+6) = (5,7,9).

What does "magnitude" mean?

The vector's length, calculated as the square root of the sum of its squared components (the Pythagorean theorem generalized to any dimension).

Does this work for 2D vectors?

Yes — enter just two components (e.g. "3,4") for a 2D vector.
