1 x 10 x 10 x 10 x 9 = 9000
1 = it must be 2
10's = any digits
9 = any digit BUT zero

What makes an irrational number different from a rational number?
A rational number cannot be expressed as a ratio of two integers, the second of which is positive.
What are all the odd positive integers?
any odd number >0 that is a whole numberSince there are infinitely many odd positive integers, you will understand that I cannot list all of them, however, they look like this: 1, 3, 5, 7, 9, 11, 13, 15, etc.Answer:The odd positive integers are those that satisfy the equation: Iodd=1+2nWhere: Iodd= Any odd positive integer valuen=any positive integer value
Why you cannot write irrational numbers in fraction?
Because that is the definition of irrational numbers: They are the numbers that cannot be written as a ratio of two integers! A fraction is a ratio of two integers.
What is a number that cannot be expressed as a quotient of 2 integers?
5
What is a number that cannot be written as a quotient of two integers?
Pi
What are two positive integers that have a sum of -18 and a product of 88?
Two positive integers cannot have a sum which is negative!
What can you conclude about the signs of two integers whose product is positive and negative?
The product of two integers cannot be "positive and negative".
What is the maximum and minimum of positive integers?
minimum is '0' and maximum cannot be defined
How many even 3-digit positive integers can be written using the digits 1 3 4 5 and6?
If a digit can be repeated there are 5 x 5 x 5 = 125 possible numbers If a digit cannot be repeated there are 5 x 4 x 3 = 60 possible numbers.
What is the difference between directed number and integers?
Directed numbers have a positive or negative sign associated with them. (The positive sign may be implied). They can be rational fractions (including mixed numbers) or irrational. Integers cannot be fractions or irrational.

Is it never always or sometimes the sum of two positive integers is zero?
The sum of two positive integers is never zero. The sum of two numbers a and b can only be zero if a=-b, or a=0 and b=0. Since 0 is not a positive integer, and a and b cannot both be positive integers if a=-b, then it is impossible for the sum of two positive integers to be zero. _______________________________________________________________ The above answer is correct. Here is another way to say it: An integer is any whole number including negative numbers, positive numbers and zero. However, a "positive integer" is a whole number greater than zero. The "sum of two positive integers" means you are adding two numbers greater than zero together. Therefore, the sum of two positive integers can never be a negative integer, and can never be zero. Example: 1 + 1 = 2
What are all the positive integers that have precisely eleven divisors?
There are infinitely many of them, and so they cannot be listed. They will be of the form n10 where n is any positive integer. Except for n=1. There are infinitely more than these, too, for example any number which is the product of eleven different prime numbers.
What characteristic can integers have that whole numbers cannot?
Integers can be negative.
Is 0.1 a integer?
Integers are whole numbers, either positive or negative. They cannot be fractions or decimal numbers.
How many 7-digit phone numbers can be formed if the first digit cannot be 0 and any digit can be repeated?
