Vector Addition Calculator

Use this vector addition calculator to add vectors and subtract vectors in 2D or 3D. It works as an adding vectors calculator, add vectors calculator, vector sum calculator, and vector subtraction calculator.

Add and Subtract Two Vectors

Enter the x, y, and z components of vectors A and B. The results update automatically.

Vector Inputs

Use “.” as the decimal separator.

Results

A + B = (Ax + Bx, Ay + By, Az + Bz)
A − B = (Ax − Bx, Ay − By, Az − Bz)
Vector x y z
A + B
A − B
Meaning of the result

Enter two vectors to calculate their vector sum and vector subtraction instantly.

Vector Addition Diagram

The diagram shows vector addition using the head-to-tail method. Vector B starts at the tip of vector A, and the resultant A + B runs from the origin to the final tip. For 2D vectors, set both z-components to 0.

x y A B A + B

Vector Addition and Subtraction Formulas

A + B = (Ax + Bx, Ay + By, Az + Bz)
A − B = (Ax − Bx, Ay − By, Az − Bz)
  • Ax, Ay, Az = components of vector A
  • Bx, By, Bz = components of vector B
  • A + B = vector sum
  • A − B = vector subtraction result

This calculator adds and subtracts vectors component by component for both 2D and 3D cases.

How to Use the Vector Addition Calculator

  1. Enter the x, y, and z components of vector A.
  2. Enter the x, y, and z components of vector B.
  3. The calculator automatically finds A + B and A − B.
  4. For 2D vectors, enter 0 for both z-components.
  5. You can also use the Calculate button for a manual refresh.

Examples

Example 1: 3D vector addition

Let A = (5, -6, 3) and B = (-7, 0, 10).

A + B = (5 - 7, -6 + 0, 3 + 10) = (-2, -6, 13)

A − B = (5 - (-7), -6 - 0, 3 - 10) = (12, -6, -7)

Example 2: 2D vector addition

Let A = (4, 1, 0) and B = (2, -3, 0).

A + B = (6, -2, 0)

A − B = (2, 4, 0)
