Matchstick puzzles with answers to improve your brain.

Explanation :

 Move one matchstick from the first + sign to 1 
The equation becomes   
II - II + III = III

Explanation :

 Move one matchstick from 9 and place it to 5, which becomes 3 and 9 respectively. 
Now, the equation we get is 3*3 = 9

Explanation :

 Take one stick from right-hand side 77 and one stick from middle 77 and create a + sign in between the middle 77, which becomes 7+1   the correct equation we get is 77 - 7 + 1 = 71.

Explanation :

 Move one stick from 9 to + sign, which becomes +,
again move one stick forward from 9, which becomes 2,             
the correct equation we get is 1 + 1 = 2. 

Explanation :

 Move one stick from II and make it square root. So we get the correct equation.

Explanation :

 The Largest Number would be 511108. 
Move two horizontal matchsticks from frist zeros, as a result, it becomes 11. 
Then, create 1 between 11 using the matchsticks which were removed to make 111 as shown in the below image.

The Smallest Number would be -91108. 
Move one from 111 matchsticks as a result it becomes 11. Then, using the two matchsticks which were removed, use one of them to make 9 out of 5 and use the second one for the ?- ?sign in front of 9.

Explanation :

 Move one matchstick from the + sign to 6, which becomes 8. So, we get the correct equation.

Explanation :

 Move one stick from the 3rd + sign to 13, i.e. 3 becomes 9, the whole number becomes 19. So, the final equation we get is-
10  + 11  +  12  -  19 = 14.

Explanation :

 Make "v" of 'II'. 
So, we get the correct equation as shown below. 

Explanation :

 Move one stick from '4' and shift it to a - sign, which becomes +.
Next,create '4 into 7, as shown in the below image. 
The correct equation will get 7+1=8.

Explanation :

 See the matchsticks number carefully, 
the number 8 has 6 joints, 
the alternate number 9 has 5 joints, 
the number 5 has 4 joints, 
3 has 3 joints, 
7 has 2 joints, 
therefore the next number in the line that should have 1 joint which is 1. 

Explanation :

 Let's add the sticks,
Add 1st matchstick to the 1st number 3 and make it 9.
Add 2nd matchstick to the last number 5 and make it into 9.
So, we get the correct equation as below : .
9-0=9

Explanation :

 Move 1 matchstick from 4 to make it 11. So, we have correct equation - 311+89=400.

Explanation :

 When we multiply 3 by 3, we get 9. This means that the square of 3 is 9. 
To visually represent this, we can add one matchstick to the upper right side of the numeral 3, transforming it into 9. In doing so, we illustrate the concept of the square of 3.

Explanation :

 Move one stick from the + sign and move it to five so, It becomes 9 - 7 = 2.
