[Interesting] Collection of Math Quiz Problems (21–30)
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?
Please calculate the following expression.

This is a quiz featuring a complex arithmetic problem with subtraction and multiplication that once appeared on a junior high school entrance exam.
For problems like this, there is a fixed order of operations—multiplication and division first, then addition and subtraction—so you can solve them by following the correct order.
However, there’s actually a rule you can use to compute the answer more quickly.
Even if you solved the problem but didn’t spot the rule, learning it could help you use your time more efficiently on entrance exams or tests.
What is the measure of angle ABC?

This is a type of problem where you find angles in geometric figures, as learned in middle school math classes.
These problems are often asked in various contexts, ranging from simple to extremely difficult.
Many people—students and adults alike—find them challenging, not because of calculation, but because they require strong reading comprehension.
Here, we will solve problems starting from easy ones, with careful, step-by-step explanations.
This way, even students and adults who struggle with these problems can study and review them in an accessible way.
What is the area of the triangle?

This is a quiz on finding the area of triangles, a topic learned from the middle to upper grades of elementary school.
Even if it used to be an easy question to answer, many adults find it surprisingly hard to get the correct answer when it’s presented as a quiz.
Here, we explain an easy way to arrive at the answer without doing detailed calculations, using an actual problem from a junior high school entrance exam.
As you work through it and reflect, you might make new discoveries—it could be more interesting than you expect.
In conclusion
How was the math quiz? Even people confident in their math skills probably found many of the problems quite challenging.
Even when you think, “Normally it should be like this,” seeing the answers makes you realize there were things you hadn’t actually considered.
Math quizzes are great mental exercises, so keep tackling more of them from now on!
