contract test2 {
    function performOperations(int256 a, int256 b) external pure returns (int256, int256, int256, int256, int256) {
        int256 sum = a + b;
        int256 difference = a - b;
        int256 product = a * b;
        int256 quotient = a / b;
        int256 remainder = a % b;

}

 运行很简单，输入两位数，然后点击call
