Thought-Process to Discover Knowledge

Welcome to **nub****trek**.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

To make best use of nubtrek, understand what is available.

nubtrek is designed to explain mathematics and science for young readers. Every topic consists of four sections.

nub,

trek,

jogger,

exercise.

This captures the small-core of concept in simple-plain English. The objective is to make the learner to think about. continue

Trekking is bit hard, requiring one to sweat and exert. The benefits of taking the steps are awesome. In the trek, concepts are explained with exploratory questions and your thinking process is honed step by step. continue

This captures the essence of learning and helps one to review at a later point. The reference is available in pdf document too. This is designed to be viewed in a smart-phone screen. continue

This part does not have much content as of now. Over time, when resources are available, this section will have curated and exam-prep focused questions to test your knowledge. continue

In this page, commutative property of vector addition is explained.

Starting on learning "Commutative Property of Vector Addition". ;; In this page, commutative property of vector addition is explained.

What does 'commute' mean?

- to go to and fro on a regular basis
- is it an English word?

The answer is 'to go to and fro between two places on a regular basis'.

Vector addition is the addition of components. The components are real numbers. If the vectors are swapped in a vector addition, will the sum be same?

- the result will be same
- the result will change

The answer is 'the result will be same'. The real numbers are commutative. The components of vectors are real numbers and so vectors are commutative.

**Commutative Property of Vector Addition: ** For any vector `vec a, vec b in bbb V`

`vec a+vec b =vec b + vec a`

Exercise

Given that `vec p + vec q = 2i-1.2j+.5k`, Which one of the following is `vec q + vec p`?.

- `.5i-1.2j+2k`
- `.5i+2j-1.2k`
- `2i-1.2j+.5k`
- `-1.2i+.5j+2k`

The answer is '`2i-1.2j+.5k`', since vector addition is commutative.
