The operation* represents either addition, subtraction, or multiplication of integers, what is the value of 1*0?

(1) 0*2=2

(2) 2*0=2

l Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient

l Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient

l BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

l EACH statement ALONE is sufficient

l Statements (1) and (2) TOGETHER are NOT sufficient

这道题目答案是A，但是我选择D。

逻辑如下：

0*2=2 ==> *为+ ==〉1*0 = 1

2*0=2 ==〉*为+或者- ==> 1*0 = 1

请指教，谢谢。

我也有这个问题哦，题目问的是what is the value of 1*0?值是多少，(2) 2*0=2中*代表+或-都能算出1*0的值，应该是选D
