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
Answer:A
恩...這題太簡單了沒人問過...
可是我覺得答案是錯的...我覺得是D
statement 2也可知是subtraction or addition
so value of 1*0=>1-0=1 or 1+0=1..
難道不能有兩種possibilities?even though the answer's the same?
