    6 divided by six plus six = 7

    I’m pretty sure it is: 6+(6/6) = 7

    If I can arrange three sizes in a three dimensional space with two “6”s lined up one to one and the third one in perpendicular to one end of this, it creates a 7- when you look from far- i got this idea from the beautiful golden “6” given in the question!

    6+6+6 = 18, 8-1=7… that was my firt choice, But I like 6+(6/6) much better, is cleaner!

    Wow to the 666 is the number of the devil and there are 7 layers of hell. Well I thought it had something to do with playing card like 3 sixes make a seven pair but thats wrong

    6 times three is 18. Subtract the 1 from the 8 and you have 7!
