The farthest number from zero is the greatest number.

Formally, the difference between two numbers, x and y, is abs(x - y) which is never negative. If the two numbers are the same then the difference is 0 else it is positive. If you define the difference as x - y then it is positive if x > y, 0 if x = y and negative if x < y.

-- Ignore the signs. -- Divide the first fraction by the second fraction, then decide whether the answer is positive or negative. -- If both numbers in a division have the same sign, then the quotient is positive. So the quotient is positive, and you're done.

If all three numbers are positive then the product obviously has to be positive. If TWO of the three numbers are negative, then the product is also positive. But if exactly ONE of the three numbers is negative or if all THREE are negative, then the product must be negative. In general, a product of numbers is negative if an ODD NUMBER of the terms is negative.

ANY positive number is greater than any negative number. Imagine you are digging a hole, and piling up the dirt you remove from the hole. The hole represents negative numbers- it goes lower than the surface. The piled up dirt represents positive numbers- it is higher than the surface. The surface is zero- neither positive or negative.

The positive number is always greater.

You subtract the smaller from the larger. The difference between 11 and 45 is found by adding negative 11 to positive 45 +45 -11 ----. +34

The sum of two positive numbers is always positive, and the sum of two negatives is always negative. If you have a positive and a negative number, there sum can be either, so look at the absolute values to decide. For example -3+2=-1. Since all you care about is the sign, look at the absolute value. If the negative number has a greater absolute value, the sum is negative and if the positive number's absolute value, which is the number itself, is bigger, the sum is positive. If the absolute values are equal, the sum is 0.

The sum of two negative numbers is positive and the sum of two negatives is negative. If you have both positive and negative numbers the sum can be either so look at the absolute value. If the negative number has a greater absolute value, the sum is negative. If the positive number has a greater absolute value the sum is positive. If the absolute values are equal, the sum is zero.

2 is a prime number because it is only divisible by 1 and itself.Ex:1*2=2It is the only even prime number and the smallest prime number!Yes and 2 is the only even prime number

the answer is a positive because two negative or two positive is always positive.
