1.	MATHEMATICSLet us see whether this property is true for integoFollowing are some pairs of integers. Observe theStatement( 17 + 23 = 40(m) (-10) + 3 =(m) (-75) + 18 =(iv) 19+(-25) = -6(v) 27 + (-27) =(vi) (-20) +0=(vi) (-35) +(-10) =What do you observe? Is the sum of two integers aDid you find a pair of integers whose sum is not anSince addition of integers gives integers, we say intIn general, for any two integers a and b, a+bis3.2 Closure under Subtractionrence is also an integer?at happens when we subtract an integer from anothve the following table and complete it:
