好吧，问题就在这里。我必须编写一个 MIPS 程序，从用户那里获取 2 个输入数字。然后，我必须编写一个代码来输出用户输入的 2 个数字的乘积、商和余数。
现在，这非常简单。但是，我没有意识到我们不能在程序中使用乘法和除法操作数。现在我不知道该怎么做，因为我很困惑如何在没有乘法和除法操作数的情况下做到这一点。我在整个程序中只使用了两次，它工作得很好，但我的教授不会接受它，现在我很难过。任何帮助，将不胜感激。谢谢
这是我的代码
# Given positive integers a and b, output a/b and a%b.
.data
str1: .asciiz "Enter a: "
str2: .asciiz "Enter b: "
str3: .asciiz "a/b = "
str4: .asciiz "a%b = "
str5: .asciiz "a*b = "
newline: .asciiz "\n"
.text
