Yes, (x > 0 and x < 10) is the same as ((x > 0) and (x < 10)) Yes, (x > 0 or x < 10) is the same as ((x > 0) or (x < 10)) Yes, (x > 0 or x < 10 and y < 0) is the same as (x > 0 or (x < 10 and y < 0))

For the first two expressions we can use the fact that the precedence of comparison operator is greater than the precedence of and and or operators. For the third expression we can use the fact that the precedence of and operator is greater than the precedence of or operator hence we can parenthesize the and operator separately.
