Fill in the blanks using the different properties.
(1) $a+b=.....$(2) $(a+b)+c=...........$
(3) $a+ ......... =0$(4) $|-a|=......$ given $a>0$
(5) $a+.......=a$
Given :
The expressions with blanks are given.
To do :
We have to fill the banks by using suitable properties.
Solution :
1. $a+b = b+a$ (commutative property)
2. $(a+b)+c = a+(b+c)$ (Associative property)
3. $a+(-a) = 0$ (Additive inverse)
4. $|-a| = a$, given $a > 0$ (Modulus of a number)
5. $a+0 = a$ (0 is additive identity)
