複合數的意思、翻譯和例句

是什麼意思

「複合數」是數學中的一個術語,指的是大於1的整數,且可以被其他整數整除,除了1和它自己以外。這意味著複合數具有至少三個正因數。與之相對的是「質數」,質數只有兩個正因數:1和它自己。複合數的例子包括4、6、8、9、10等。

All even numbers greater than 2 are composite numbers.

例句 3:

在數學中,了解複合數的性質對於學習因數非常重要。

In mathematics, understanding the properties of composite numbers is crucial for learning about factors.

2:Non-prime Number

用法:

這個術語用來描述不是質數的整數,這意味著它們有多於兩個的因數。這個術語常常在數學教學中使用,幫助學生區分質數和複合數。

例句及翻譯:

例句 1:

4和6都是非質數,因為它們可以被其他數字整除。

4 and 6 are non-prime numbers because they can be divided by other numbers.
