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.

Positive x Positive =Positive Positive x Negative= Negative Negative x Positive= Negative Negative x Negative =Positive

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

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.

You can solve this in two ways.1) Trial and error. That is, try multiplying two consecutive integers; if the product is too large, try smaller integers; if the product is too small, try larger consecutive integers. 2) Call the two consecutive integers "n" and "n+1", and solve the equation: n(n+1)=210

Because it is.

The answer depends on which properties are being used to prove which rules.

When multiplying integers, multiplying by the same sign will always produce a positive integer. Such as a negative times a negative equals a positive. If the signs are different then the product will be a negative.

The rules are not the same.Multiplication is commutative whereas division is not.Multiplication is associative whereas division is not.

They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.

Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered. Your "question" sheds no light on what rules for integers you are interested in: rules for addition, subtraction, and so on; rules for multiplying numbers with integer indices, and so on.

Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.

In every possible way- because whole numbers and integers are the same.
