Why when you multiply and negative number and a positive number it always equals a negative number?
This happens because a negative number is dominant over a positive one, so the number will multiply just as if you were multiplying even numbers, but at the end, just put a negative symbol. Also, if you multiply two negatives, they cancel themselves out, and the answer just becomes positive, but that only goes when multiplying an even amount of negative numbers together. For all of these, do the equation the same way, but at the end you may have to just add or take away a negative or positive symbol.
If you divide a negative number by a negative number will you get a positive number?
You will end up with a positive number. With integers, if you multiply or divide an even amount of negative numbers, the answer will be positive and if you multiply or divide an odd amount, the answer will be negative.
How do you multiply numbers ending in zero?
You add a zero at the end of the factor
What is the sum if you multiply two rational numbers?
Either way, you'll end up with a rational number, but you won't get a sum if you multiply.
What different numbers are there in maths?
There is no end to the numbers of maths and there are many classifications of numbers, like primes, fractions, even, odd, positive, negative and others.

How do you multiply a negative number to a positive number?
A negative times a positive is always a negative. The rest is the same: just multiply as if they are both positive numbers and then add the negative sign at the end.
If you divide a negative number by a negative number will you get a positive number?
You will end up with a positive number. With integers, if you multiply or divide an even amount of negative numbers, the answer will be positive and if you multiply or divide an odd amount, the answer will be negative.
What is the sign of the product of 11 negative integers and 2 positive integers?
The 2 positive integers don't affect the sign. Every time you multiply by a negative number, the sign changes, so you have negative, positive, negative, positive... Since the number of negative numbers is odd, the end result is negative.The 2 positive integers don't affect the sign.

Why -2 times minus 2 equals plus 4?
When you multiply two negative numbers together, the result is a positive number. This is because each negative number can be thought of as the opposite of a positive number. So, when you multiply -2 by -2, you are essentially finding the product of the opposite of 2 and the opposite of 2, which results in a positive 4.
How do you multiply numbers ending in zero?
You add a zero at the end of the factor
Is the product of two positive mixed numbers ever less then 1?
No. A mixed number must be greater than 1, and two numbers that are greater than one that are multiplied together end up being greater that either number by itself.
Why are there 90 2-digit positive integers?
Integers are whole numbers (including zero) and their negatives. I = {..., -2, -1, 0, 1, 2, ...} The positive integers are restricted to just: P = {1, 2, 3, ...} The two digit numbers in this set begin at 10 and end at 99. To count them, simply subtract and add one: 99 - 10 + 1 = 90. Or, count starting at 11 and you'll end up with 89, then add one more for 10 to get 90. :)
Do your numbers end?
Numbers are infinite in both all directions - infinitely negative, infinitely positive and infinitely imaginary.
Is the product of 169 negative numbers positive or negative?
Negative. Every pair of negative numbers gives a positive multiple. Positive numbers do not affect the sign any further, so you can throw out pairs of numbers from 169. In the end, there will be just the one negative number left.
What is the sum if you multiply two rational numbers?
Either way, you'll end up with a rational number, but you won't get a sum if you multiply.
