Answer 1

A 3+3+5+1-2-5=5
B 5+ 8 +3=16
C 7+ 3- 4= 6
D 14+ 16: 2= 14+ 8=22

Answer 2

$a).|3|+|-3|+|-5|+|-1|-|-2|-|-5|= \\ =3+3+5+1-2-5= \\ =6+5+1-2-5= \\ =11+1-2-5= \\ =12-2-5= \\ =10-5= \\ =5$
$b).|8-3|+|8|+|-3|= \\ =|5|+8+3= \\ =5+8+3= \\ =13+3= \\ =16$
$c).|7|+|-3|-|-4|= \\ =7+3-4= \\ =10-4= \\ =6$
$d).14+|-16|:|-2|= \\ =14+16:2= \\ =14+8= \\ =22$
