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.

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:
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:
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:
