键盘输入三个整数和两个算术运算组成的表达式，计算结果。 运算符包括：加+,减-乘*,除/ 输入格式: 三个整数，两个运算符，组成算数表达式，输入的字符之间没有空格 输出格式: 在表达式的后边输出=计算结果

为了实现这个功能，你可以编写一个简单的程序，例如用 Python 编程，通过字符串处理解析输入的表达式，然后按照优先级计算结果。这里有一个基本的例子：

def calculate_expression(expression):
    # 定义运算符优先级
    priority = {"+": 1, "-": 1, "*": 2, "/": 2}

    def apply_operator(operators, values):
        operator = operators.pop()
        right = values.pop()
        left = values.pop()
        if operator == "+":
            values.append(left + right)
        elif operator == "-":
            values.append(left - right)
        elif operator == "*":
            values.append(left * right)
        elif operator == "/":
            try:
                values.append(left / right)
            except ZeroDivisionError:
                print(f"Error: Division by zero not allowed")
                return None

    operands = []
    operators = []

    for token in expression:
        if token.isdigit():
            operands.append(int(token))
        elif token in priority:
            while (operators and priority[token] <= priority[operators[-1]]):
                apply_operator(operators, operands)
            operators.append(token)
        elif token == ")":
            while operators[-1] != "(":
                apply_operator(operators, operands)
            operators.pop()

    # 处理剩余的运算符和操作数
    while operators:
        apply_operator(operators, operands)

    # 返回最终结果
    return operands[0] if len(operands) == 1 else "Invalid expression"

# 示例输入
expression = input("请输入一个表达式 (e.g., 5+3*2): ")
result = calculate_expression(expression)
if result is not None:
    print(f"{expression} = {result}")
