Addition is one of the four fundamental mathematical operations. The sum of the given expression is 0.
Addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
The sum of the given expression can be done without performing addition by opening the parenthesis, which will change the nature of the number. therefore, we can write,
[5.5 + (-2.3)] + (-5.5 + 2.3)
= (5.5 - 2.3) - 5.5 + 2.3
= 5.5 - 2.3 - 5.5 + 2.3
Since the sum of two same magnitude opposite numbers is 0. Therefore,
= 0
Hence, the sum of the given expression is 0.
