Can You Solve This 6 Number Problem?
Can you solve this number problem? Make each of the following equations true using any mathematical symbols, but you cannot use numbers: 0 0 0 = 6, 1 1 1 = 6, 2 2 2 = 6, 3 3 3 = 6, 4 4 4 = 6, 5 5 5 = 6, 6 6 6 = 6, 7 7 7 = 6, 8 8 8 = 6, 9 9 9 = 6. Here's an exampleyou can add a plus and minus sign to 6 6 6 = 6 to make it true. It would then be 6+66=6. And because you may not use numbers to make these equations true, you cannot use cube roots (involved drawing a three), exponents (involved numbers), etc. There is not necessarily one way to solve each equation.
