How to use Add Vectors
- 1. Paste your vectors. Enter one vector per line in the input pane, written as components in parentheses like (1, 2, 3). Every vector needs the same number of components to be added together.
- 2. Check the component count. The tool sums each position across all the vectors you supplied, so a list of five 3D vectors returns a single vector whose components are the running totals of each dimension.
- 3. Read the resulting vector. The output shows one combined vector in the same parenthesized format you used for input, ready to drop straight into further calculations or another tool.
- 4. Copy the sum. Copy the resulting vector from the output pane into your notes, code, or the next calculation step in your workflow.
When to use Add Vectors
Add Vectors sums any number of vectors component by component. It is the operation behind combining forces in physics, stacking displacement vectors, or adding up velocity contributions from several sources at once.
- Combining physics forces. A mechanics problem lists several force vectors acting on an object and asks for the net force. Paste each force as a line and read off the single resultant vector.
- Stacking displacement steps. A game or robotics script moves an object through a sequence of small displacement vectors and you want the total displacement without writing a throwaway script to sum them.
- Verifying a linear algebra answer. You worked out a vector addition problem by hand for a course and want a fast second opinion before you move to the next exercise in the problem set.
- Merging sensor readings. Several accelerometer or wind readings arrive as separate 3D vectors and you need their combined total to estimate overall motion or force direction.

About the Add Vectors tool
Add Vectors does its work locally, right in the browser. Sum of vectors. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Math Tools collection on EditSafely, a set of 234 small, focused Math utilities that share the same instant, private workspace.
There is nothing to configure. Provide the input and the result appears on its own. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Is Add Vectors free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
