Below given is a blank equation:

____ + ____ = ____

you are given digits 1,2,3,4,5,and 6

Use each only once once without any mathematical operator other than the ones provided in the equation to make this equation true.

Each digit must be used in every solution.

I know of three solutions. Can you provide more?

Could we use fractions or dots here? (i.e 16/4, 3.2)

Fractions are not allowed. But you can use the digits in some other manner ;)

4^3 + 1^2 = 65

If you write it in classic mathematical manner, you don't need to use '^' which is used for programming.

Well i'm stumped.

Every possible combination and didn't get anything.

I'm thinking that we need to switch to a different base to make the equation true. Base 6? I'll have to get back to this one.

Below given is a blank equation:

____ + ____ = ____

you are given digits 1,2,3,4,5,and 6

Use each only once once without any mathematical operator other than the ones provided in the equation to make this equation true.

Each digit must be used in every solution.

I know of three solutions. Can you provide more?

Isn't raising a number to a power (i.e., exponents) a mathematical operation, too? Yet, you say not other mathematical operations, and even say that fractions aren't allowed. Maybe I'm just too new, but this is confusing.

I think it's because you don't need to write an operator, just the exponent. It's a little confusing, but I guess that was his intention. He wrote "operator" and we assumed "operation".

You need to change the base.

14+36=52 Base 8

15+26=43 Base 8

16+25=43 Base 8

16+34=52 Base 8

24+35=61 Base 8

25+16=43 Base 8

25+34=61 Base 8

26+15=43 Base 8

34+16=52 Base 8

34+25=61 Base 8

35+24=61 Base 8

36+14=52 Base 8

I tried a bunch of other bases, and base 8 is the only one that works.

You told not to use any mathematical operator than + and == so ^ is also a mathematical operastor. Isnt it?

you are considering this operator thing too seriously..this is just rearranging the digits in another manner
