  • good job very intelligent young man

  • propostures 

  • GOOD JOB MY FRIEND!

  • bullshit

  • i draw numbers like that thank you very much

  • Very cute and ofc what an intelligent child! Congrats to the parents or whoever assists the child to unfold his talents. However...it looks like the kid is writing with his WRONG hand? Perhaps allowing him to write with his left, will cause less a struggle for him. A detail really but, it almost hurts me to watch.

  • who draws 7's like that? like really? jkjk lol

  • @AngryCritter9 yes, there are 24*2=48 solutions, I calculated :)

  • i dont get it at all .... wtf ?! 4 numbers = always the same , all 4 need to become 25 , right ? WAT IS THE POINT I DONT GET IT , hahahahaha

  • u can also have:

    10 5 7 3

    7 3 10 5

    3 7 5 10

    5 10 3 7

    And then the corners become 25 too
