As an expert in mathematical notation and semantics, I'm here to clarify the concept of "at most" in the context of mathematical expressions. The phrase "at most" is often used to describe a limit or an upper bound on a quantity or a condition that is not expected to be exceeded.
### English Explanation:
When we use the term "at most," we are essentially saying that something is "less than or equal to" a certain value. This is a common way to express a maximum limit or cap. In mathematical notation, this is often represented by the symbol "≤", which is read as "less than or equal to." The symbol is a combination of a less-than sign ("<") and an equals sign ("="), indicating that the value on the left can be either less than or equal to the value on the right.
The notation "a ≤ b" means that "a" is less than or equal to "b." It asserts that "a" can take on any value that is less than "b" or it can be exactly "b." This is a way of saying that "a" does not exceed "b" under any circumstances.
The concept of "at most" can also be extended to other contexts such as probability, where it might describe the maximum probability of an event occurring. In set theory, it could relate to the maximum number of elements in a set.
The symbol for "less than or equal to" can be represented in various ways in different fonts and typefaces, but its meaning remains consistent across mathematical literature. It is also important to note that the symbol "≤" has a Unicode representation, which is "U+2264". This allows for consistent representation across different digital platforms and documents.
In some contexts, you might see a variation of this symbol where the greater-than sign (">") is bisected by a vertical line, which is another way to denote "not greater than." This is less common but still conveys the same meaning as "at most."

当我们使用术语“至多”时，我们实际上是在说某个事物是“小于或等于”某个值。这是表达最大限制或上限的常见方式。在数学符号中，这通常由符号"≤"表示，读作“小于或等于”。该符号是小于号（"<"）和等号（"="）的组合，表明左侧的值可以是小于右侧的值，或者恰好等于右侧的值。
符号"a ≤ b"意味着“a”小于或等于“b”。它断言“a”可以取任何小于“b”的值，或者正好是“b”。这是一种说法，表明“a”在任何情况下都不会超过“b”。
“至多”的概念也可以扩展到其他上下文，例如在概率论中，它可能描述事件发生的最大概率。在集合论中，它可能与集合中元素的最大数量有关。
"小于或等于"的符号在不同的字体和字形中可以以不同的方式表示，但其含义在数学文献中保持一致。同样重要的是要注意，符号"≤"有一个Unicode表示，即"U+2264"。这允许在不同的数字平台和文档中进行一致的表示。
在某些上下文中，您可能会看到这个符号的一个变体，其中大于号（">"）被一条竖线分割，这是表示“不大于”的另一种方式。这不太常见，但仍然传达了与“至多”相同的意义。

The notation a -- b means that a is less than or equal to b (or, equivalently, not greater than b, or at most b); "not greater than" can also be represented by the symbol for "greater than" bisected by a vertical line, "not." (The unicode for -- is "U+ 2264".)
