For any integers a, what is `(-1)xx` a equal to ?

For any integer a , what is [(-1) xx a] equal to?

For any integer a, is a+(-1)=-a ?

For any integer a,is: a-:(-1)= -a ? Take different values of 'a' and check.

For any integer a, is: a -: 1=1? Take different values of 'a' and check.

state true or false. Write the reasons. For any two integers a and b,a xx b = b xx a

We know that any real number x can be expressed as followig x=[x]+{x} , where [x] is an integer and 0 le {x} lt 1 . We define [x] as the greatest integer less than or equal to x or integer part of x and [x] as the fractional part of x. Suppose for any real number x, we write x=(x)-(x) , where (x) is integer and 0 le (x) lt 1 . We define (x) as the least integer greater than (or) equal to x. For example (3.26) =4(-14.4)= - 14(5)=5 elearly, if x in I then (x)=[x] . If x !in I , then (x)=[x]+1 we can also define that x in ( n , in +1) rArr (x)=n+1 , where n in I The domain of defination of the function f(x)=(1)/(sqrt(x-(x))) is
