The Vietnamese word "số không" translates to "zero" or "nought" in English. It is used to refer to the number 0, which represents the absence of quantity or value.

Basic Usage:

1. As a Number:

   • "Số không" is used in mathematics to indicate the number that comes before one.
   • Example: "Hai trừ hai bằng số không." (Two minus two equals zero.)

2. In Counting:

   • It signifies that there are no items or nothing in a set.
   • Example: "Tôi có số không quyển sách." (I have zero books.)

Advanced Usage:

• In Mathematics:

  • "Số không" can also be used in algebra, calculus, and other advanced math contexts to represent a neutral element in addition or an identity element.
  • Example: "Trong phép cộng, số không không thay đổi giá trị của số khác." (In addition, zero does not change the value of another number.)

• In Everyday Contexts:

  • It can be used metaphorically to indicate a lack of something, such as success or progress.
  • Example: "Năm ngoái, tôi có số không thành công trong công việc." (Last year, I had zero success in my job.)

Variants:

• "Không" alone can also mean "not" or "no," depending on the context, and it is often used in negative constructions.
  • Example: "Tôi không biết." (I do not know.)

Different Meanings:

• "Số không" can specifically refer to the numerical representation, whereas "không" can express negation or absence in broader contexts.

Synonyms:

• While "số không" is specific to the number zero, you might encounter "không" in phrases that communicate the idea of nothingness, but it’s important to note that "không" alone does not refer to the number zero.

Summary:

In summary, "số không" is a fundamental term in both mathematics and everyday language in Vietnamese, representing the concept of zero.
