try them all
lets see multiplication
1x0=0 in ur set
1x1=1 in ur set
0x1=0 in ur set
0x0 =1 in ur set
all values apears to be in ur set thus its closed
OpenStudy (anonymous):
b&d
OpenStudy (anonymous):
lets try division
1/0 undefined
0/1=0
1/1=1
0/0 = undefined
undefined seems to be not in ur set thus its not closed
OpenStudy (anonymous):
b and d are wrong
