Problem Solving Challenges
1. Largest Number
What is the largest number you can write using three digits? You may use a digit more than once.
Hint: What about exponents?
Answer
Answer/solution: .
Using nines for each digit, there are four choices: 999, 999, 999, and .
999 = 999
999 = 913517247483640899
999 = 29512665430652752148753480226197736314359272517043832886063884637676943433478020332709411004889
has over 356,000,000 digits.
2. Handy Man
A man walks into a hardware store. He buys 1 for a dollar, 50 for two dollars, and 200 for three dollars. What is the man buying?
Hint: Think about Amazon Deliverables.
Answer
Answer/solution: House numbers (decals).
Typical guesses include nuts, bolts, nails, washers, etc. Actually, the 1 is made up of one digit, 50 is made up of two digits, and 200 is made up of three digits. Each digit (decal) costs $1. Therefore, if your house number is 200, then you would need three digits, which would cost $3.
