小学数学1-10英语解释， 求翻译，谢谢。

不是网上的内容，是孩子数学书上的，英语不好解释不了，特来求助。

1 First number --One is not a prime number. It's called the "multiplicative identity", because any number multiplied by 1 gives that number as the answer.

2 Even prime number --The number 2 is the only even-numbered prime number - a number that is only divisible by itself and 1。

3 Triangular number --This is smallest triangular number, which is a positive whole number that is the sum of consecutive whole numbers. So, 1+2=3。

4 Composite number --The number 4 is the smallest composite number - a number that is the product of other numbers. The factors of 4 are two 2s.

5 Prime number --This is the only prime number to end with a 5. A 5-sided polygon is the only shape for which the number of sides and diagonals are equal.

6 Perfect number --This is the smallest perfect number, which is a number that is the sum of its positive divisors (except itself). So, 1+2+3=6.

7 Not the sum of squares --The number 7 is the lowest number that cannot be represented as the sum of the squares of three whole numbers (integers).

8 Fibonacci number --The number 8 is a cube number(2^3=8) and it is the only positive Fibonacci number, other than 1, that is a cube.

9 Highest decimal --The number 9 is the highest single-digit whole number and the highest single-digit number in the decimal system.

10 Base number --The Western number system is based on the number 10. It is speculated that this is because humans used their fingers and toes for counting.

很奇怪，不教加减乘除 情况下小孩能理解这个10个数字的解释吗？

比如8 = 2*2*2 不会乘法 怎末理解 8 is a cube number. 而且 还要懂 8 是Fibonacci number 中的一个 那就要懂加法 3+5 =8

很好奇这里的老师怎末教.

这个是他买的一本小学帮助做作业的数学书上第一页对数字的解释，看的我流汗了。。。。

试着自己翻译了一下，还是有些看不懂

1 First number --One is not a prime number. It's called the "multiplicative identity", because any number multiplied by 1 gives that number as the answer.
第一个数字，1不是素数。它被称为“乘法单位”，因为任何数乘以1给出了数字作为答案。

2 Even prime number --The number 2 is the only even-numbered prime number - a number that is only divisible by itself and 1。
偶素数 数字2是为一个的一个偶数素数，一个只能被自己和1整除的数。

3 Triangular number --This is smallest triangular number, which is a positive whole number that is the sum of consecutive whole numbers. So, 1+2=3
三角数 最小的三角数，正整数是它前面两个连续数字之和。

4 Composite number --The number 4 is the smallest composite number - a number that is the product of other numbers. The factors of 4 are two 2s.
合数？？ 4是最小的合数？-------------------后面的看不懂

5 Prime number --This is the only prime number to end with a 5. A 5-sided polygon is the only shape for which the number of sides and diagonals are equal.
素数， 这是唯一的以5结尾的素数。一个五角星型是唯一对角线相等的多边形？？

6 Perfect number --This is the smallest perfect number, which is a number that is the sum of its positive divisors (except itself). So, 1+2+3=6.
完美数？ 最小的完美数，积极除数？？----------------看不懂

7 Not the sum of squares --The number 7 is the lowest number that cannot be represented as the sum of the squares of three whole numbers (integers).
非平方和数，数字7是最低的不能被平方和代表的整数。

8 Fibonacci number --The number 8 is a cube number(2^3=8) and it is the only positive Fibonacci number, other than 1, that is a cube.
斐波那契数，8是立方数，唯一的正斐波那契数？？除了1是立方数？？------看不懂

9 Highest decimal --The number 9 is the highest single-digit whole number and the highest single-digit number in the decimal system.
最高的十进制数，在十进制系统里9是最高的十进制个位数

10 Base number --The Western number system is based on the number 10. It is speculated that this is because humans used their fingers and toes for counting.
基础数？西方计数系统以10为基础，推测是因为人类祖先使用手指作为计数开始。

4 Composite number --The number 4 is the smallest composite number - a number that is the product of other numbers. The factors of 4 are two 2s.
合数？？ 4是最小的合数？-------------------后面的看不懂
=> 后面是解释什么是合数，合数是其他数字相乘得到的积，4的因数是两个2。

5 Prime number --This is the only prime number to end with a 5. A 5-sided polygon is the only shape for which the number of sides and diagonals are equal.
素数， 这是唯一的以5结尾的素数。一个五角星型是唯一对角线相等的多边形？？
=> 5边形正好有5个对角线，边的数量跟对角线的数量相等。而4边形只有2个对角线，6边形有9个对角线。

6 Perfect number --This is the smallest perfect number, which is a number that is the sum of its positive divisors (except itself). So, 1+2+3=6.
完美数？ 最小的完美数，积极除数？？----------------看不懂
=> 完全数，6是最小的完全数，所谓完全数就是一个数正好等于它所有（除它本身的）的正因数的和。所以，1+2+3=6。
又比如1+2+4+7+14=28。

8 Fibonacci number --The number 8 is a cube number(2^3=8) and it is the only positive Fibonacci number, other than 1, that is a cube.
斐波那契数，8是立方数，唯一的正斐波那契数？？除了1是立方数？？------看不懂
=> 斐波那契数：0 1 1 2 3 5 8 13 21 34 55 ……
8是除了1以外唯一一个既是立方数又是正的斐波那契数。
