Mrs. Shine was having a rough day and wanted a break. So she asked her class to calculate the sum of the first 50 odd numbers. In a few moments, Winifred was at her desk with the correct answer of 2,500. Stunned, Mrs. Shine figured she must have gotten lucky, and sent precocious Winifred back to her seat with the task of finding the sum of the first 75 odd numbers. Again, Winifred returned in seconds with the correct answer (5,625).
How did Winifred find the answer so quickly?
Winifred, being the precocious child she is, realized there was a pattern when computing smaller sums of odd numbers.
First 3: 1 + 3 + 5 = 9
First 4: 1 + 3 + 5 + 7 = 16
First 5: 1 + 3 + 5 + 7 + 9 = 25
Do you see the pattern like our dear friend Winnie?
For the first n odd numbers, the sum is equal to n2 . Thus the first 50 is 502 , or 2,500, and the first 75 is 752 , or 5,625.

If you could chose to increase the average fuel economy of a car, which of these would save the most fuel?
1. 10mpg -> 12mpg
2. 12mpg -> 15mpg
3. 15mpg -> 20mpg
4. 20mpg -> 30mpg
5. 30mpg -> 60mpg
It turns out they all save the same amount of fuel.
If you travel 100 miles:
100 / 10 = 10 gallons used
100 / 12 = 8 1/3 gallons used
10 – 8 1/3 = 1 2/3 gallons saved
100 / 30 = 3 1/3 gallons used
100 / 60 = 1 2/3 gallons used
3 1/3 – 1 2/3 = 1 2/3 gallons saved

A dad offered to pay his son $5 for every correct answer on his math test. His son said he would pay his Dad $8 for every incorrect answer. There were 26 questions on the test and no money was exchanged.
How did this happen?
The son got 16 questions correct and missed 10. This means he owed his Dad 10 * $8 = $80, but his Dad owed him 16 * $5 = $80, so it was a wash.
Two math equations to solve it are x + y = 26 and 5x = 8y.

Nothing specific,
but more than a few.
This many clustered
together will do.
Bunch. It’s a vague term that means more than a few. And clustered items like bananas, grapes or celery come in bunches.

Toby likes indigo but not red. He likes onions but not turnips. He likes forms but not shapes.
According to the same rule, does he like tomatoes or avocados?
Toby only likes words that start with prepositions, like his name. Thus he likes tomatoes, not avocados.

I am enjoyed by some, despised by others. Some take me for granted, some treasure me like a gift. I last forever, unless you break me first.

In a textile factory, 5 machines take exactly 5 minutes to make 5 shirts. How many minutes will it take 100 machines to produce 100 shirts?
5 minutes. It takes each machine 5 minutes to make a shirt, so if you have all 100 machines running at the same time, they’ll produce the 100 shirts in 5 minutes.

What is the answer to this math problem:
8 ÷ 2 (2 + 2)
16 or 1, depending.
According to PEMDAS, parentheses come first: 8 ÷ 2 (4)
Then, even though multiplication is first in PEMDAS, you go left to right: 4 (4) = 16
If you got 1, you’re in good company. That’s what I got at first too but most calculators I’ve tried get 16.
I found this at Popular Mechanics and the debate continues online.
