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, vector additive identity is explained.

Starting on learning "Vector Additive Identity". ;; In this page, vector additive identity is explained.

What does 'identical' mean?

- same; similar; alike
- different; mismatch

The answer is 'same; similar; alike'

Consider the vector `vec 0 = 0i+0j+0k`. What will be the result of adding that with another vector `vec a`?

- `-vec a`
- `|vec a|`
- `0i+0j+0k`
- same as `vec a`

The answer is 'same as `vec a`'. The sum is *identical* to the vector being added.

The vector `vec 0 = 0i+0j+0k` is also known as .....
