The numbers from 20 to 100 use the numbers 1 to 9, preceded by a tens number
30 thirty (31 thirty-one, 32 thirty-two, etc.)
40 forty (41 forty-one, 42 forty-two, etc.)
50 fifty
60 sixty
70 seventy
80 eighty
90 ninety
100 one hundred
The numbers from 101 to 999 put a hundreds value (one hundred, two hundred) in front of the last two digits as above :
101 one hundred one
111 one hundred eleven
121 one hundred twenty-one
201 two hundred one
211 two hundred eleven
221 two hundred twenty-one
1000 one thousand
The numbers 1001 to 999,999 put the thousands value (one thousand, two thousand, eleven thousand, one hundred thousand) as a separate number followed by thousand), then the number as from 1 to 999.
1001 one thousand one (also one thousand and one)
1011 one thousand eleven
1111 one thousand one hundred eleven
9999 nine thousand nine hundred ninety-nine
10000 ten thousand
11000 eleven thousand
21000 twenty-one thousand
21111 twenty-one thousand, one hundred eleven (note comma often used)
110000 one hundred ten thousand (also one hundred and ten thousand)
111000 one hundred eleven thousand (also one hundred and eleven thousand)
999999 nine hundred ninety-nine thousand, nine hundred ninety-nine
There are 168 prime numbers between 1 & 1000.
There are 900 three-digit whole numbers between 1 and 1000
1 = 11000 = 1111101000
76,127

101,102, ....200
The numbers 1001 to 1999 add "one thousand" in front of the three-digit numbers 1 to 999. The number 2000 is "two thousand." See the related question (1 to 1000) below.
square numbers 1 to 1000
I believe that the rule is you spell out numbers one through nine, and then use numbers for 10 and above.
I spell them correctly.
There are 168 prime numbers between 1 & 1000.
It is 1000*(1000+1)/2 = 500500
That depends what those nine numbers are. If the numbers are 992, 1, 1, 1, 1, 1, 1, 1, and 1, then it is easy.If the numbers are all 9s, then it can be written 999 + (999 / 999) = 1000.
The easiest way to find out how many numbers are in between two points that form a range of numbers (i.e. How many numbers are in between 1 and 1000), is to subtract the first point from the second point and subtract one.Such as 1-1000 would be 1000 - 1 is 999, minus 1 is 998. Therefore there are 998 numbers between 1 & 1000.
There are 31 perfect square numbers between 1 and 1000 (including 1).
