查詢過了沒這題
Q3:
For all positive integers m and v, the expression m Θ v represents the remainder when m is divided by v. What is the value of {(98Θ33) Θ17} - {98Θ(33 Θ17)}=?
A.-10
B.-2
C.8
D.13
E.17

答案是 D。 完全解不出來，求救....

題目說m Θ v 代表m和v相除所得到的餘數
例如:(98Θ33)就是98/33=2...32 (98Θ33)就是代表32
所以
{(98Θ33) Θ17} - {98Θ(33 Θ17)}
=(32Θ17)-(98Θ16)
=15-2=13
