give him a break...

T = true (1)
F = false (0)

逻辑与 (true when only both are true)
T && T = T
T && F = F
F && F = F

逻辑或 (false when only both are false)
T || T = T
T || F = T
F || F = F

逻辑非
!T = F
!F = T

了解一下操作符优先级(precedence and order of evaluation)

10>4&&!(100 T && !F || T
T && T || T
T

10>4&&!(100 T && !F && T
T && T && T
T (你给的答案不对)

You'll probably have more trouble when it's time for bitwise operation.
