Math quiz for adults. Can you solve it? (31–40)

Arithmetic Quiz

[Genius if you can solve it in elementary school] Get every question right and you’re a math master!
Arithmetic Quiz

If an elementary school student can solve these, they’re a genius! Here are some ideas for a math quiz.

The quiz contains 50 questions that test your math skills.

It’s perfect for people who love math or are good at calculation problems.

Since there are 50 questions, you might want to take breaks or refresh yourself along the way.

There are four difficulty levels in total, with questions tailored to each level.

For example, there’s a question like “What is the answer to 3 + 4?” with four choices.

It’s also a good idea to prepare a notebook and pen before you start.

It’s an extremely difficult problem that would be almost impossible to solve under normal circumstances.

For someone with a rich imagination or a knack for flashes of insight, it might be easy, but for those who aren’t good at using mathematical formulas, it could be a bit challenging.

Even so, it’s impressive that the answer can be derived like this.

Coin Counting Quiz

[Coin Count] A quiz that tests your dynamic vision and calculation skills!
Coin Counting Quiz

This is a quiz where you keep adding the amounts of coins as they spread out and guess the total.

Coins that were hidden underneath show up later, and you have to watch and count while calculating, so it actually uses more brainpower than you’d think.

Doing two things at once is really tough, isn’t it? But somehow I feel more motivated when it’s shown with money rather than just plain calculations—maybe that’s because I’m a bit of a money-grubber.

Verbal arithmetic SEND MORE MONEY

[Challenging Quiz] A cipher-like calculation puzzle! The classic alphametic SEND MORE MONEY (logic puzzle / IQ test / brain exercise)
Verbal arithmetic SEND MORE MONEY

SEND MORE MONEY is a cryptarithm puzzle meaning “send more money,” created by the puzzle maker Henry Dudeney in 1924.

Each letter corresponds to a single digit, and the same letter always represents the same digit.

It’s quite fun to deduce each digit step by step as you work toward the solution.

Give it a try and solve it patiently.

In conclusion

How was the quiz for adults? There were some difficult questions, but there were also ones where trickiness and flashes of insight were key.

You might have felt frustrated when you had to check the answers for the ones you couldn’t solve.

But as you work through more questions, your mind will loosen up and your intuition will sharpen! Try lots of them and have fun!
