### Types of math riddles and how to solve them

There are many types of math riddles, such as arithmetic riddles, algebra riddles, geometry riddles, logic r iddles, number riddles, and word riddles. Each type of riddle may require different strategies to solve them, but here are some general tips that can help you with any math riddle:

Read the riddle carefully and identify the given information and the question.

Look for clues or patterns in the riddle that can help you narrow down the possible solutions.

Use logic and reasoning to eliminate any solutions that do not make sense or do not fit the given information.

Try different approaches or methods to solve the riddle, such as drawing a diagram, making a table, using algebra, or working backwards.

Check your solution by plugging it back into the riddle and see if it satisfies all the conditions.

## Examples of math riddles for different levels and abilities

To give you an idea of what math riddles look like and how to solve them, here are some examples of math riddles for different levels and abilities. Try to solve them on your own before looking at the answers below.

### Easy math riddles for kids

#### Riddle 1: How do you make the number 7 even without addition, subtraction, multiplication, or division?

Answer: You can make the number 7 even by removing the letter S from it. Then it becomes even (EVEN).

#### Riddle 2: How many times can you subtract the number 5 from 25?

Answer: You can only subtract the number 5 from 25 once. After that, you are subtracting 5 from 20, then 5 from 15, and so on.

### Medium math riddles for teens

#### Riddle 3: I have a calculator that can display ten digits. How many different ten-digit numbers can I type using just the 0-9 keys once each, and moving from one keypress to the next using the knights move in chess?

Answer: A knights move in chess is a move that forms an L-shape, two squares horizontally and one square vertically, or two squares vertically and one square horizontally. To find the answer, we need to count how many ways we can start with any digit and then make nine knights moves to form a ten-digit number. For example, one possible way is to start with 1 and then move to 6, 8, 3, 7, 9, 4, 2, 5, and end with 0. Another possible way is to start with 0 and then move to 5, 2, 4, 9, 7, 3, 8, 6, and end with 1. To count all the possible ways, we can use a table like this:

123

456

789

0

In this table, each cell represents a digit on the calculator. We can mark each cell with a number that indicates how many ways we can reach that cell using knights moves from any previous cell. For example, we can mark the cell with 1 with a zero because there is no way to reach it using knights moves from any previous cell. We can mark the cell with 6 with a one because there is only one way to reach it using knights moves from any previous cell (from cell with 1). We can mark the cell with 8 with a two because there are two ways to reach it using knights moves from any previous cell (from cell with 1 or cell with 3). And so on. The table will look like this:

000

001

020

1

The final answer is the sum of all the numbers in the table, which is four. Therefore, there are four different ten-digit numbers that can be typed using just the 0-9 keys once each and moving from one keypress to the next using the knights move in chess.

#### Riddle Riddle 4: When my dad was 31, I was just 8 years old. Now his age is twice as old as my age. What is my present age?

Answer: To solve this riddle, we need to find the difference between my dad's age and my age when he was 31 and I was 8. The difference is 31 - 8 = 23 years. This means that my dad is always 23 years older than me, no matter what our current ages are. Now, we can use this information to set up an equation that relates our current ages. Let x be my present age and y be my dad's present age. Then we have:

y = 2x (because his age is twice as old as my age)

y - x = 23 (because the difference between our ages is always 23 years)

We can solve this system of equations by substituting y = 2x into the second equation and get:

2x - x = 23

x = 23

Therefore, my present age is 23 years old.

### Hard math riddles for adults

#### Riddle 5: An insurance salesman walks up to a house and knocks on the door. A woman answers, and he asks her how many children she has and how old they are. She says I will give you a hint. If you multiply the 3 childrens ages, you get 36. He says this is not enough information. So she gives a him 2nd hint. If you add up the childrens ages, the sum is the number on the house next door. He goes next door and looks at the house number (13) and says this is still not enough information. So she says shell give him one last hint which is that her oldest of the 3 plays piano. Why would he need to go back to get the last hint after seeing the number on the house next door?

Answer: To solve this riddle, we need to find all the possible combinations of three positive integers that multiply to 36 and add up to 13. There are only two such combinations:

1, 6, and 6

2, 2, and 9

The salesman knows this, but he still cannot tell which one is the correct one because both combinations have the same sum (13). However, when the woman tells him that her oldest of the three plays piano, he realizes that the correct combination must be 2, 2, and 9 because this is the only one that has a unique oldest child. If the combination was 1, 6, and 6, then there would be two oldest children who are both 6 years old.

#### Riddle 6: Lily is a lilypad in a small pond. Lilly doubles her size each day, On the 20th day she covers the whole pond. On what day was Lily half the size of the pond?

Answer: This riddle may seem tricky at first, but it can be solved by using some simple logic. If Lily doubles her size each day, then on the day before she covers the whole pond, she must have covered half of it. Therefore, on the 19th day, Lily was half the size of the pond.
