[Interesting] Compilation of Math Quiz Problems (11–20)
Intuitive Math Quiz
We’re introducing an intuitive math quiz that tests your ability to estimate.
In this quiz, you’re asked to solve fairly complex expressions within a short time limit.
Writing out the equations is prohibited—you must arrive at the answer instantly, using only mental calculations.
However, since the answers are multiple-choice, you don’t need to fully solve every expression; it’s fine to make an educated guess.
If you want to adjust the difficulty, try simplifying the equations or reducing the number of choices.
Four integers?
This is a problem that appeared in a past Arithmetic Olympiad.
The problem itself is aimed at elementary school students, but when you actually try to solve it, it turns out to be quite challenging.
It involves adding and subtracting the four provided two-digit integers to find the answer, and rather than calculation skills, it requires reasoning and logical thinking, so some adults may also find it difficult.
However, once you notice the numerical patterns, it becomes easy to solve, and needless to say, it feels very satisfying once you get it.
[Challenging] Math Quiz
![[Challenging] Math Quiz](https://i.ytimg.com/vi/sry6ocXhFP0/sddefault.jpg)
No matter their age, many people probably struggle with arithmetic or math.
Some are great at calculations but completely stumble on word problems.
This time, most of the questions are word problems and a bit more challenging than what you studied in school, but don’t worry—the quiz is followed by detailed explanations, so even if you’re not confident, you can review comfortably and learn while having fun.
If you’re good at math, it’s fun to tackle the problems on your own; if you’re not, try gathering with friends and taking on the challenge together.
Sum of the areas of a square and an equilateral triangle
This is a problem about finding the area of a figure.
Many people may know how to find the area of a single shape, but here we need to find the area of a complex figure that combines an equilateral triangle and a square.
Those who aren’t confident with this might hesitate at first glance, but if you notice that all the side lengths are the same regardless of the shape, you can solve it very easily.
It’s useful for study from elementary school students to adults, and it’s a good bit of trivia to remember.
How long did the round trip take?
This is a problem where you calculate the time taken for a round trip.
If you apply the formula “time = distance/speed,” it should be relatively easy to solve.
Various numbers appear, but what you need are the distance and the speed.
Then just take into account that it’s a round trip and you’re done.
Since it’s a trick quiz, let’s answer it calmly.
This quiz tests whether you can think straightforwardly.
With knowledge at about a 6th-grade level, you can solve it, so it could be fun to try it together with your child.
Some of you may have been taught it as the ‘HA-JI-KI’ rule.
Monty Hall problem
It’s a quiz where you choose one of three doors or boxes, the host reveals a dud from the other two, and then you decide whether to switch your choice or stick with it.
If you can figure it out at first glance, you could be said to have considerable mathematical talent.
Many people may not immediately grasp it even after seeing the answer.
To solve this problem, it’s important to change your perspective.
We tend to focus only on the winning option, but it becomes clearer if you look at the losing side first.
Should you switch, or should you stay? Your reasoning will be put to the test.

A math quiz with answers that can vary
What’s the answer to “9×9÷9×9”? The result changes depending on the order of operations.
How do you think it should be calculated correctly? Elementary school kids who are learning this in real time might come up with the answer right away.
But adults might find themselves thinking, “Huh? Where do I start the calculation?” Should you go from left to right, or do the multiplications first? Please think it through and try to find the answer.
Problems that look simple like this can really make you overthink, can’t they?
