Let's use N to represent any number.
- N x N = N
- N x -N = -N
- -N x -N = N
So the rules are:
- A positive integer times a positive integer will be a positive integer
- A positive integer times a negative integer will be a negative integer
- A negative integer times a negative integer will be a positive integer.

The quotient of two negative integers is?
It's a positive number. Here's the rule: In multiplication and division . . . -- If both numbers have the same sign, then the result of multiplying or dividing them is positive. -- If the two numbers have different signs, then the result of multiplying or dividing them is negative.
What are the rules for multiplying integers?
Positive x Positive =Positive Positive x Negative= Negative Negative x Positive= Negative Negative x Negative =Positive
Multiplying integers with fractions?
Let's say that you were multiplying 10 by 2/5 , you would turn the 10 into 10/1 which is still equal to 10 then you multiply 10/1 and 2/5 by multiplying the numerators (the top numbers) and the denominators (the bottom numbers) 10*2/1*5 = 20/5 = 4
Are odd integers less than ten prime?
No. 9 is an odd integer less than 10 and you can get it by multiplying 3X3. All odd integers less than 9 are prime. Except one (1). The number 1 is neither prime nor composite.
Is the product of two integers positive negative or zero How can you tell?
The product of two integers will be: * Zero, if one factor, or both, are zero. * Positive, if both factors have the same sign (both positive, or both negative) * Negative, if the two factors have different signs. Actually, these rules apply to all real numbers, not just to integers.
