สวัสดีปีใหม่ $2559$ ครับ

$\phantom{0}0 = 2\times (5-5) \times 9$
$\phantom{0}1 = 2-5-5+9$
$\phantom{0}2 = 2 \times (5+5-9)$
$\phantom{0}3 = 2+5+5 - 9$
$\phantom{0}4 = -(2\times 5)+5+9$
$\phantom{0}5 = 2+5-5+\sqrt{9}$
$\phantom{0}6 = (2\times 5)+5-9$
$\phantom{0}7 = -2+5-5+9$
$\phantom{0}8 = -2+ (5\div 5)+9$
$\phantom{0}9 = 2\times (5-5)+9$
$10 = (25+5)\div\sqrt{9}$
$11 = 2-5+5+9$
$12 = 2+(5\div 5)+9$
$13 = \sqrt{25}+5+\sqrt{9}$
$14 = (2 \times 5) - 5+9$
$15 = 2+5+5+\sqrt{9}$
$16 = (\sqrt{25}\times 5) -9$
$17 = -2+5+5+9$
$18 = 2+ (5\times 5) - 9$
$19 = \sqrt{25}+ 5+9$
$20 = 2\times 5\times (5-\sqrt{9})$
$21 = 2+5+5+9$
$22 = 2+[5\times (-5+9)]$
$23 = 2\times (5+5)+\sqrt{9}$
$24 = (2\times 5) +5+9$
$25 = (2\times 5)+(5\times\sqrt{9})$
$26 = (2+5)\times 5-9$
$27 = 25+5-\sqrt{9}$
$28 = (2+5)\times (-5+9)$
$29 = 2\times (5+5)+9$
$30 = 2+(5\times 5)+\sqrt{9}$
$31 = 25+\lceil\sqrt{5}\rceil+\sqrt{9}$
