Isn’t Math Wonderful? – January 2025

2025: What a Year!

Seems like every year, we have lots of fun facts to discover about the year number, and 2025 is NO exception!! Here are some of the fun facts to get us started:

• 2025 = 45² (Enjoy this ‘square’ year. Unless you were born in 1936 or before, it’s the only one most of us will have!)
• 2025 = 5² * 9²
• 2025 = 1³ + 2³ + 3³ + . . . + 9³
• And there are others (including some special dates!): See this short video for some more!
• And here’s two dates missed in the video above:
  • Jan 5, 25 = 1/5/25 = 5⁰/5¹/5²
  • Jan 9, 25 = 1/9/25 = 1²/3²/5²
  • And I’m sure there are more!!

Reminder: I’ve done this in past years, so I’ll do it again. You’ve perhaps ‘heard’ me say that every day is mathematically special. And I’ll offer again: Send me your birthday (without the year, if you prefer), and I’ll send you at least one mathematically interesting thing about that date.
