Advances in Mathematics: Matrices in Microsoft Office

Introduction

• Dr. Robinson discusses advances in mathematics focusing on matrices today utilizing Microsoft Office.
• The session will cover common issues in Microsoft Office and solutions to navigate those hiccups.

Key Steps in Working with Matrices

• Starting with Word Version:
  • Use Ctrl + Home to start at the top of the document.
  • Navigate using down arrow key.

Matrix Definition

• Given matrices:
  • Matrix A: 2x2 Matrix
    • Row 1: 2, 4
    • Row 2: 1, 2

Inputting Matrices in Microsoft Office

• Use Alt + J then E for the equation menu.
• Example input command:
  • Input sequence to write Matrix A:
    • \begin{pmatrix}
    • Followed by the numbers with & to separate columns and \ to indicate line breaks.
• Close matrix with \end{pmatrix}.

Converting Matrix Format

• Convert to linear or professional format using Alt + J and then C for conversion:
  • Linear format allows for editing corrections.
  • Professional format displays the matrices beautifully.

Working with Braille Displays

• Braille mode allows quick navigation and editing of matrices:
  • Use CapsLock + Space for Braille math editor.
  • Navigate using Braille display keys to edit matrix elements.

Example of Finding Matrix C

• To find Matrix C such that C = A + B:
  • Addition of corresponding elements:
    • Row 1: 2 + 1, 4 + 3
    • Row 2: 1 + 1, 2 + 2
  • Resulting Matrix C: 2x2 matrix with correct sums.

Common Issues

• Auditory Feedback: Sometimes, parts of the matrix may not read correctly (e.g., it may skip reading a matrix element).
• Solution: Ensure proper line breaks and formatting to enhance readability.

Tips for Efficiency

• Keep a secondary document open for manual calculations as you process through matrix operations.
• This helps in quickly recalling answers when required later in the calculations.

Conclusion

• The session aims to empower users in using Microsoft Office effectively for matrix calculations, while also highlighting common challenges and providing solutions.
• Next session will introduce Math Kicker for faster matrix operations.
