How do I use the numbers 2,3,6,7 to get 10? You can also make numbers like 23 or 76 too.

    $\begingroup$ Could you also specify what operations are allowed? Are exponents allowed? Are factorials allowed? $\endgroup$

Using basic operations and a two digit number:

$6\times7-32=42-32=10$

Just using the four basic operations:

$(7-2)\times\frac 63$

You didn't specify whether exponents and factorials are allowed so I'm assuming they are. I found 2 answers:

1:

$ 3^2 - 6 + 7$

2:

$ 7 + 2 + \frac{3!}{6} $

  • $\begingroup$ @bobble I didn't know answering such questions is also not allowed. I guess I'll read through the policy again to see if there is anything else I missed $\endgroup$

  • $\begingroup$ The policy is to close such questions. Closing prevents answers. This has no effect if the question gets answers before closing. Thus, users are encouraged to not answer questions which are close-worthy. I'm not sure if it's an official policy or not, but it's my strong opinion. My comment was to reflect that strong opinion. $\endgroup$

  • $\begingroup$ @bobble That makes sense. I guess I got too excited that there was finally a puzzle easy enough for me to solve $\endgroup$
