A recommended activity for preventing dementia in older adults is doing arithmetic problems.
By doing calculations, you train the brain’s cognitive functions, which can help prevent dementia.
In this article, we introduce arithmetic exercises that are great brain training for seniors.
We’ve compiled problems that support dementia prevention, including addition and subtraction, read-aloud calculation exercises, and quick-response calculation tasks.
Since calculation problems really make you use your brain, it’s important to take it slow and keep at it steadily without overexerting yourself.

For dementia prevention! Brain-training arithmetic quiz for seniors (11–20)
three-digit addition
This is a workbook where three three-digit numbers appear, and you have to add them up within 20 seconds.
Since you need to calculate at a good pace, it should be quite the brain workout.
The format is mental arithmetic, so get some paper and a pen ready and give it a try! Doing so might naturally exercise your fingertips as well.
Using this method as a reference, for example, you could prepare lots of cards with three-digit numbers, draw them like playing cards, and calculate with the numbers you get—that could work too.
Fill-in-the-blank numbers: “Please make the total ◯◯.”
Let me introduce a fill-in-the-numbers puzzle that’s fun, like logic rules.
There’s a 3-by-3 square grid, and the rule is to fill the blanks so that the sums of each row and column match the target numbers.
Start by practicing with smaller numbers.
Once you get used to it, try increasing the target numbers or using two-digit numbers in the cells.
It’s a bit complex, but there’s actually a trick: fill in one cell first, then figure out the rest.
Give it a try!
Division problem
Many people probably feel uneasy about division.
Why not try overcoming that by tackling a video quiz packed with one division problem after another? Compared to addition and such, set aside plenty of time and give it a real try.
Even when you’re thinking things through slowly, your brain is working, so it’s not wasted time—it’s brain training.
Once you can solve division problems quickly, you’ll likely start enjoying them.
Solving any problem is refreshing and gives you that satisfying feeling, doesn’t it?
small change calculation
Let me introduce a brain-training exercise that uses counting coins: the Coin Calculation game.
Coins will appear on the screen—memorize them within the time limit and calculate the total amount.
The double task of taking a quick look, memorizing, and then calculating greatly activates your brain.
Calculating and paying money are essential activities for living in society.
In fact, it has been reported that in the early stages of dementia, counting coins becomes difficult, leading people to rely more on bills.
If you’ve had fewer chances to shop in your daily life, please give this a try.
Let’s complete the equation! Fill-in-the-blank math problems
Rather than looking at an equation and deriving the answer, this is a type of problem where part of the equation is left blank, and you fill in the missing piece by looking at the remaining numbers and the answer.
It’s a perfect kind of calculation exercise for brain training, isn’t it? Let’s start with single-digit addition and subtraction that you can solve in a few seconds.
There are plenty of fill-in-the-blank problems on video sites as well; they come at you quickly like a stream, but even if you don’t know the answer, just thinking about them serves as brain training, and you gradually pick up the knack.
Try it in whatever way feels easiest for you.
Dice calculation problem
This is a calculation puzzle using dice faces.
A die has numbers from 1 to 6, so addition should be easy, right? However, in this puzzle, you add the numbers on the opposite faces of the visible dice.
On a standard die, each pair of opposite faces sums to 7.
The opposite of 1 is 6, and the opposite of 2 is 5.
So if the problem shows 1 + 6 on the dice, you add their opposite faces and the answer is 11.
There’s a bit of a trick to it, so it’s not straightforward and can be challenging at first, but once you get used to it, it may become surprisingly easy to solve!

Calculation Quiz
We would like to introduce a “calculation quiz” that cultivates logical thinking, memory, and arithmetic skills.
There are four problems in total; the answers to three are known.
The final problem provides a hint, and it’s a quiz where you deduce the answer by working through the calculations leading up to it.
Starting from the answer and working backward, you calculate which numbers fit into the parts marked with symbols such as circles and squares, and you need to remember the numbers used along the way.
Because it requires performing multiple activities simultaneously, it provides stimulating content for the brain.
There is also a time limit, so it’s important to proceed calmly without rushing.
In conclusion
How was the brain-training math exercise? It might take you some time at first, but once you get used to it, you’ll be able to solve the problems. Don’t rush—take your time and work through them. If you’re struggling with frequent forgetfulness, try doing them every day. It’s a good idea to set an achievable goal, like three problems a day, so you can keep at it without overdoing it.
