Answer:
We have to find the sum of
=107 +0+39+13
As 0 is identity element of real or natural numbers, with respect to addition.
So, adding 0 to any natural number has no effect on the Natural number.
=107+39+13
We will use associative property of Addition, which states that
a+(b+c)=(a+b)+c=a+(b+c)
=(107+13)+39
=120+39
=159
