The commutative and associative properties are helpful when adding mixed numbers because they allow for flexibility in rearranging and grouping the numbers. The commutative property lets us change the order of the mixed numbers being added without affecting the sum, while the associative property lets us group different parts of the numbers together for easier calculation. This can simplify the addition process, particularly when dealing with fractions and whole numbers in mixed numbers. By using these properties, we can efficiently find a sum without getting confused by the complexity of the numbers.
For example, by adding 1 + 1 + 1 ... (a total of 100 times).
Adding and subtracting integers is a specific case of adding and subtracting rational numbers, as integers can be expressed as rational numbers with a denominator of 1. The fundamental rules for adding and subtracting integers—such as combining like signs and using the number line—apply similarly to other rational numbers, which can include fractions and decimals. The operations are governed by the same principles of arithmetic, ensuring that the properties of addition and subtraction, such as commutativity and associativity, hold true across both integers and broader rational numbers. Thus, mastering integer operations provides a solid foundation for working with all rational numbers.
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).

To get multiples of 12, start at 12 and keep adding 12.
Addition is adding or counting items together. It becomes habit after practicing and often can then be done in the head. To learn to add start by using counters.
Performing one's complement addition involves adding two binary numbers by first taking the one's complement of the subtrahend and then adding it to the minuend. This method differs from traditional binary addition because it eliminates the need for subtraction by using complement arithmetic.

The parallelogram method is a graphical technique used in vector addition. It involves constructing a parallelogram using the two vectors to be added, with the diagonal of the parallelogram representing the resultant vector. The magnitude and direction of the resultant vector can be determined from the properties of the parallelogram.
You could do 16.2 + 16.2 + 16.2 + 16.2 but why do it that way when 16.2*4 is so much easier? 64.8
