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.

The newborn giraffe's weight is 65,000 grams
Given:
The newborn giraffe weight is 65 kilograms (kg).
How much does it weigh in grams (g)?
We know that, 1 kilogram = 1000 gram.
In order to convert kilograms to grams, we just do multiplying
To simplify, there is an order system to convert:
We cancel the kilogram (kg) because it is both in top and the bottom.
Kilogram (kg) and gram (g) are the most common unit of mass in metric system of measurement.
