I was reading the quick tutorial here:http://logos.cs.uic.edu/366/notes/mips%20quick%20tutorial.htm

它说在我使用mult $t0, $t1之后，结果存储在Hi和Lo中，我知道这些是mult和div的特殊寄存器，但是如何访问它们?

It says after I use mult $t0, $t1 the results are stored in Hi and Lo, I understand these are special registers for mult and div, but how do I access them?

让我说我做mult $t0, $t1，其中$t0和$t1都是2.如何得到结果? (4)

Lets say I do mult $t0, $t1 where $t0 and $t1 are both 2. How do I get the result? (4)
