Introduction
Elementary operations refer to the changes made to rows and columns for a desired effect.
Pre-Requisites:
Addition, subtraction and multiplication of rows and columns in a matrix.
Activity:
Transforming a row or column leaves the other rows and columns unaffected.
Real Life Question:
Can elementary operations be used to find out inverse of a matrix code program in computing?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Interchange | Interchanging a row or column with another row or column means swapping of the row or column. |
| Elementary transformations | Changes made to matrices to achieve a desired effect. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Dice | Using Dice one can replicate a matrix format. Place dice in a manner that it would show a 2x2 format. Attempt different transformations. |
Real life uses :
A change in the price row can show changes in demand row.
