Moving matchsticks

I made this calculation with some matchsticks. But it's incorrect, something's gone wrong. I think I put one matchstick in the wrong place.

By only moving one matchstick how can I correct this calculation?

How many different answers can you find?

    1. Yes, but read the question carefully Tiara. Move one matchstick to make the calculation work.

  4. If you move bottom on the left side it will give you five and add it to the the top of the four to make it nine.

  6. To make four you have to take the middle stick from the six to make four. the calculation is 4+0=4

    1. Yes good work Javan. This definitely works.

      Make sure you use spaces in your name though, your name isn't Javan6red, it's Javan (from) 6 Red!

  7. Great teamwork Year 6. You have found three different solutions.

    Do you think there are any more?

    If there are, what are they?

    And if there aren't, can you prove that we've found them all?

  8. You should move the stick on the left on the 6 so it makes 5 and put that stick on the top of the 4 so it makes 9 5+4=9

  9. You have to take it from the plus sign and then add it onto the six so it turns into eight and the 8-4=4 .

  10. You can do 5+4=9 by moving a matchstick from the 6 to make a 5, and then you put it on the 4 to make 9.

  11. What you need to do is remove the matchstick from the add sign then it will become, 8-4=4 and the mistake is that 6+4=10

  12. 8-4=4
    You can move the matchstick from the add sign and put it with six to make 8

  13. What you need to do is remove the one of the matchsticks from the plus and add it to the six witch makes 8 so 8-4=4

  14. What the answer is 8-4=4 or 5+4=9 and the wrong answer is 6+4=4 because its 6+4=10

  15. 5+4=9
    6+9=15
    6+4-4=6
    8+4-4=8

  16. You need to take away the add to the six so it will be eight and 8-4=4.

  17. The six you just take the middle one then it turns into 5 and then you add it onto the answer then it euqles 9 so the met herd is 5-4=9.
