How are decimals different from whole numbers?
Decimals include a fractional part, represented by digits to the right of the decimal point, while whole numbers only have a whole part, represented by digits to the left of the decimal point. Whole numbers can be positive or negative, while decimals can also be fractions or mixed numbers. Additionally, whole numbers are used to count while decimals are used for measurement and precision.
How many numbers are possible using 3 digits?
I believe there would be a total of 1,000 combinations possible, if you're counting 000-999. If you're only counting whole numbers 100 and up (numbers in the hundreds) I think there are 900.
What are the three smallest 7-digit whole numbers that can be made using only the digits 4309285?

How many two-digit numbers are twice the sum of their digits?

How many whole numbers have exactly 5 digits?
89999 Any whole number above 99999 has 6 or more digits, and any whole number below 10000 has 4 or less digits. Since there are only whole numbers involved, it is a simple subtraction of 10000 from 99999.
How many digits are in 1 through 39?
There are an infinite number of them. But if you only count the whole numbers, then there are only 69 of them.

An n-digit number has 4^n such numbers.
A whole number consists of the digits 2 4 6 8 and 0 If each digit is used only once how many whole numbers are possible?
There are 5 digits in 24680; think of them as 5 compartments. You can select 5 numbers for the 1st compartment, 4 numbers for the 2nd compartment, 3 numbers for the 3rd compartment, 2 numbers for the 4th compartment, and 1 number for the 5th compartment. So, the answer is 5*4*3*2*1 or 5! or 120
