Math Problem of the Week - Lower Elementary - June 6, 2021 to June 12, 2021

Lower Elementary: 

Question: There are six continents on a Risk game board. If there are 12 troops in North America, 16 troops in South America, 18 troops in Europe, 22 troops in Asia, 24 troops in Africa, and 100 troops on the board in total, then how many troops are in Australia? 

Answer: 8 troops

Solution: There are 12 + 16 + 18 + 22 + 24 = 92 troops on the board that aren't in Australia, so there must be 100 - 92 = 8 troops in Australia.
