Thought-Process to Discover Knowledge

Welcome to nubtrek.

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.

Read in the blogs more about the unique learning experience at nubtrek.

User Guide

Welcome to nubtrek.

User Guide

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.

User Guide

nub is the simple explanation of the concept.

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

User Guide

trek is the step by step exploration of the concept.

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.

User Guide

jogger provides the complete mathematical definition of the concepts.

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.

User Guide

exercise provides practice problems to become fluent in the concepts.

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.

What does 'Associate' mean?

• to connect with; to join
• to separate

The answer is 'to connect with; to join'

When three complex numbers are added,
•  Person A associates the middle complex number with first complex number and, to the result of that, he adds the third complex number (z_1 + z_2) + z_3
•  Person B associates the middle complex number with third complex number and to that she adds the first complex number z_1 + (z_2+z_3)

will the two persons get different results?

• They will get different results.
• They will get identical results

The answer is 'They will get identical results'.

Is Associative property applicable to subtraction?

• when subtraction is handled as inverse of addition.
• yes. Order of subtraction can be swapped

The answer is 'when subtraction is handled as inverse of addition'. For (z_1 - z_2) - z_3, it will be considered as (z_1 + (-z_2)) + (-z_3).

Associative Property of Complex Addition: For Any complex number z1,z2,z3 in complex numbers, z1+z2, +z3 = z1+, z2+z3
Is Associative property applicable to subtraction?
when subtraction is handled as inverse of addition.
yes;s;order
yes. Order of subtraction can be swapped
The answer is 'when subtraction is handled as inverse of addition'. For z1 minus z2, minus z3, it will be considered as z1 +, minus z2 + minus z3
Given z1, z2 in complex numbers, what will be the result of z1 + z2 + z1 ?
2 z1;2z1
2 z1 + z2
z1+z2
z1 + z2
z2
z2
2z2
z1+2 z2
The answer is ' 2z1 + z2'.
