a + b means a > b, a - b means a = b, a = b means a ≥ b, a * b means a ≤ b and a / b means a < b.According to the statementX + Y => X > YY * Z => Y ≤ Z => Z ≥ YW = Z => W ≥ Z => Z ≤ WW ≥ Z ≥ Y and X > YConclusion (I): Y * W => Y ≤ W, followsConclusion (II): X + Z => X > Z.
Which cannot be definitely determined.Conclusion (I) follows.
