[ Arithmetic operations. Numerical identities ]

Using five twos, arithmetic operations, and exponentiation, form the numbers from 11 to 15.

#
Recall the problem $\underline{98702 .}$

## Solution

$11=(22 \times(2 / 2)) / 2$,

$12=(22 / 2)+(2 / 2)$

$13=(22+2+2) / 2$

$14=2 \times 2 \times 2 \times 2-2$,

$15=22 / 2+2 \times 2$
