Not smart enough – Calca Review

79 - 10% => 78.9 the expected answer should be 71.1. If Calca does not understand the syntax it is better to show an error than to give the wrong answer. Another example, cos(0)/sin(0) => 0 which also is wrong. The answer is n/a or infinity. In addition the app crashes on me frequently. Not recommended.
