Thursday Review

Question: Using a basic calculator, find the prime decomposition of 13,475.

Solution:

• Attempt division by increasing numbers: 2, 3, 4, 5
• 5 works, so divide until it doesn’t:
  • 13,475/5 = 2,695
  • 2,695/5 = 539
• Attempt division by increasing numbers: 6, 7
• 7 works, so divide until it doesn’t:
  • 539/7 = 77
  • 77/7 = 11
• Attempt division by increasing numbers: 8, 9, 10, 11
• Only 11 worked, so 11 is prime.

Prime decomposition: $13475 = 5^2 \cdot 7^2 \cdot 11$

LaTeX Overview

• All written assignments must be submitted as PDFs typeset with LaTeX
• I highly recommend that you hand write your solutions first, before typesetting, because it is easier to think when hand writing.
• I require LaTeX because it ensures your submission is legible. Other courses also require LaTeX. Learning LaTeX is a valuable learning goal: LaTeX is essential for communicating mathematics digitally.

Activity

• Guide students through opening the written assignment on Overleaf
• For the remainder of class, typeset your solutions to the first written assignment
