In basic arithmetic, 1 + 1 equals 2 because when you combine one unit with another unit, you end up with a total of two units. Similarly, 2 + 1 equals 3 because when you add two units to one more unit, the total number of units becomes three. These equations follow the fundamental principles of addition, where the sum represents the total quantity when two or more numbers are combined. **

The root of lg(x) = 1 can be found by rewriting the equation in exponential form. The base of the logarithm is 10, so lg(x) = 1 can be rewritten as 10^1 = x. Therefore, the root of lg(x) = 1 is x = 10. **

Yes, 1 + 1 is indeed equal to 2. This is a fundamental principle of arithmetic and mathematics. The concept of addition states that when you combine two individual quantities of 1, the result is 2. This principle is universally accepted and forms the basis of many mathematical operations and calculations. **

1 1/2 stories typically refers to a house or building that has one full floor and a second floor that is partially finished or smaller in size. This type of structure often has a main level with living spaces and bedrooms, and a second level that may have additional rooms or storage space. The half-story is usually located within the roofline of the building, creating a unique architectural design. **

The answer to whether retail trade or wholesale and foreign trade is better depends on various factors such as the specific business goals, target market, and resources available. Retail trade involves selling products directly to consumers, allowing for higher profit margins but also requiring more marketing and customer service efforts. On the other hand, wholesale and foreign trade involve selling products in bulk to other businesses or overseas markets, offering the potential for larger sales volumes but with lower profit margins. Ultimately, the best choice would depend on the individual business's strengths, market opportunities, and long-term objectives. **

The 1-2-2-1 system in volleyball is a defensive formation where there is one player positioned in the back row, two players in the middle, two players in the front row, and one player in the back row. This formation is commonly used to defend against the opponent's attacks and to set up offensive plays. The players in the middle and front rows are responsible for blocking and digging, while the back row player provides defensive coverage and sets up the offense. This system allows for a balanced defensive coverage and offensive setup. **

In the context of a code or pattern, 1 3 1 2 could represent a sequence of actions or steps. For example, it could mean "do action 1, then action 3, then action 1 again, and finally action 2." Alternatively, it could represent a numerical pattern, such as a sequence of numbers in a mathematical series. Without further context, it is difficult to determine the specific meaning of 1 3 1 2. **
