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.

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

Introduction to Equations

» numerical equation is a statement equating two numerical expressions.

→ eg: `2+4-1 = 5` * Note that `2+4-1` is evaluated to `6-1` which equals `5`. *

→ eg: `4xx3-7 = 2+4-1` * Note that both sides can be evaluated to `5`**Numerical equations are not studied in detail, as the arithmetic can be performed to a number as result.*

» **Algebraic Equation**

→ a statement equating one algebraic expression to a numerical expression. eg: `2x+7=9`

→ OR a statement equating two algebraic expressions. eg: `3x-1 = 7-x`

In this pattern of squares using crayons, if the number of squares in a row is `x`, the number of crayons forming the squares `=3x+1`. Someone used 22 crayons to create such a pattern. How many squares will be made?

- given number of crayons, the number of squares cannot be calculated
- equate the number of crayons to the algebraic expression

The answer is 'equate the number of crayons to the algebraic expression'. This is explained in the next page.

The number of crayons forming `x` squares `=3x+1`. Someone used `22` crayons to create a similar pattern. The question provides that the "number of crayons used `= 22`"

We know that "the number of crayons forming squares `= 3x+1`"

Both the above are number of crayons and so can be equated.

`3x+1=22`.

This is an example of algebraic equation.

Which of the following is a meaning for the word 'equation'?

- an imaginary line along the center of the Earth
- a statement that two quantities are equal

The answer is 'a statement that two quantities are equal'.

What is the word or phrase used to refer a statement that two quantities are equal?

- Practice Saying the Answer

The answer is 'algebraic equation'.

An algebraic equation has the following.

• an equal symbol `=`

• a quantity on the left hand side (LHS) of the equal symbol.

• another quantity on the right hand side (RHS) of the equal symbol.

• One of the quantities on LHS or RHS is an algebraic expression.

• The other is in the form of algebraic expression or numerical expression or a number.

What is the terms used to refer either side of equation?

- Practice Saying the Answer

The answer is 'left hand side (LHS) and right hand side (RHS)'.

equate the number of crayons to the algebraic expression

The answer is 'equate the number of crayons to the algebraic expression'. This is explained in the next page.

The number of crayons forming x squares = 3 x+1. Someone used 22 crayons to create a similar pattern.;; the question provides that the number of crayons used = 22 ;; We know that the number of crayons forming squares equals 3 x + 1. ;; Both the above are number of crayons and so can be equated. 3x + 1 = 22. This is an example of algebraic equation.
