Question 435957
I found a way to get 81 using standard mathematical notation:


{{{81 = floor(exp(2(2.2)))}}} where {{{floor(x)}}} is the floor value function and {{{exp(x)}}} is the same as {{{e^x}}}.


Likewise,


{{{79 = floor(exp(2(2.2))) - 2}}}
{{{83 = floor(exp(2(2.2))) + 2}}}


I'll leave it to you to find a way to get 76. It might take some creativity.
