I dont understand the 12 hr clock system as a gommunative group. can anyone help me? There also other groups (closure,associative,idenity,invers and communative property)

Best ResponseYou've already chosen the best response.0commutative means to travel, to commute from one place to another; groups are commutative if you can switch them around and still retain the same value, for example: 5 + 8 = 3 8  5 = 3 ...... addition is commutative.

Best ResponseYou've already chosen the best response.0lets try multiplication: 4(9) = 36 9(4) = 36 ....... muliplication is ALSO commutative we can switch the position of the numbers and still retain the value.

Best ResponseYou've already chosen the best response.0what about division? 12/4 = 3 4/12 = 1/3 ...division is not commutative :)

Best ResponseYou've already chosen the best response.0associative is just the larger version of commutative, and it deals with associating numbers together...

Best ResponseYou've already chosen the best response.0(4+3)6 = 76 = 1 4+(36) = 4+(3) = 1 addition is associative... (3*2)*5 = 6(5) = 30 3*(2*5) = 3(10) = 30 ....multiplication is associative

Best ResponseYou've already chosen the best response.0(4/2)/2 = 2/2 = 1 4/(2/2) = 4/1 = 4 ...division is NOT associative

Best ResponseYou've already chosen the best response.0identity is like looking in the mirror... you see your own reflection. the additive identity is "0" 4+0 = 4; 2+0 = 2; (3/4)  0 = (3/4) the multiplicative identity is "1" 2(1) = 2 ; 2365(1) = 2365 ; (3/5)(1) = (3/5)

Best ResponseYou've already chosen the best response.0an inverse is the reverse of the identity....... for example: a * a^1 = 1 a +(a) = 0 the additive inverse is the opposite of the number/object. so that adding them together =0 the muliplication inverse is the reciprocal of a number. 4(1/4) = 1

Best ResponseYou've already chosen the best response.0I would say that the clock system is commutative because it doesnt matter how you add the hours together, you get the same results..... but I am not up to date on "group" theory
