# Math Teachers at Play Carnival Number 43 – Fast Food, Crime Drama and More!

Welcome! I’m Caroline Mukisa from Maths Insider and the host of the the 43rd edition of the Math Teachers at Play carnival!

I’m delighted once again to be presenting a really cool range of math related blog posts and articles. This month, you’ll get to savor math posts related to McDonalds, Dexter, war, an ancient game, an inventor and more!

Do bookmark this page so you can come back and read any of the posts you don’t get time to read right now!

### 3 Cool facts about the number 43:

1) In a survey conducted by AskKids in 2008, 43% of parents admitted to having done their kids’ homework at least once to ease the strain!

2) From Wikipedia, 43 is the largest natural number that is not a McNugget Number.

• you cannot buy 43 McNuggets at McDonald’s by combining multiples of the original packages of 6, 9, and 20 McNuggets.
• you can get 44, 45, 46, … and all larger numbers of McNuggets.
• 44 = 20 + 24 = 20 + 6×4, so you can order four packages of 6 McNuggets, and 1 pack of 20,to get 44.
• 45 is five 9-packs,
• 46 is a 6-pack and two 20s.
• But if you need to purchase exactly 43 McNuggets, you’re out of luck!

3) Also from Wikipedia, 43 is the smallest prime number expressible as the sum of 2, 3, 4, or 5 different primes:

• 43 = 41 + 2
• 43 = 11 + 13 + 19
• 43 = 2 + 11 + 13 + 17
• 43 = 3 + 5 + 7 + 11 + 17
