COMMUTATIVITY If `a and b` are any two whole numbers then `a + b = b + a.`

If A and B are any two sets, then

ASSOCIATIVITY If abc are any whole numbers then (a xx b)xx c=a xx(b xx c)

CLOSURE PROPERTY If a and b are two whole numbers then a+b is also a whole number.In other words the sum of any two whole numbers is a whole number or whole numbers are closed for addition.

ASSOCIATIVITY If abc are any three whole numbers then (a+b)+c=a+(b+c) In other words the addition of whole numbers is associative.

CLOSURE PROPERTY If a and b are two whole numbers then their product a xx b is also a whole number.

Which of the following statements are true (T) and which are false (F)? If a, b, c are any three whole numbers then a + (b + c) = (b + a) + c.

If A and B are any two sets then A-B=A nn B'

If A and B are any two sets then (A-B)uu B=A uu B

DISTRIBUTIVITY OF MULTIPLICATION OVER ADDITION If abc are any three whole numbers then (i) a xx(b+c)=a xx b+a xx c( ii) (b+c)xx a=b xx a+c xx a

If A and B are any two sets then A-B=A hArr A nn B=phi
