Its a computer language

$\\ \rm\longmapsto \dfrac{9}{81}+1+10$

$\\ \rm\longmapsto \dfrac{1}{9}+11$

$\\ \rm\longmapsto \dfrac{99+1}{11}$

$\\ \rm\longmapsto \dfrac{100}{11}$

$\\ \rm\longmapsto 9.1$

Proved

Note that /* means 1 line added means fraction .

and ++ means +1

The confidence interval is given by
$14\pm0.392$ or (13.608,14.392).

We first calculate the z-score associated with this level of confidence:
Convert 95% to a decimal: 95% = 95/100 = 0.95
Subtract from 1: 1-0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1-0.025 = 0.975

Using a z-table (http://www.z-table.com) we see that this value has a z-score of 1.96.

The formula for the confidence interval is
$\overline{x}\pm z*\frac{\sigma}{\sqrt{n}}
\\
\\14\pm 1.96*(\frac{3.2}{\sqrt{256}})=14\pm 1.96*(\frac{3.2}{16})=14\pm 0.392$
