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.

Integers can be negative or positive numbers providing that they are whole numbers without decimals or fractions.

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.

You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.

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.

The sign of the larger number will be the sign of the answer, if you're adding them together. If they're the same size, and of different signs, the answer will be zero.

First, look at the length of the numbers. If one is longer than the other, the difference is positive. If the numbers are of equal length, compare the first digits to see which is higher. Continue through the number and if all are equal, the difference is zero.

yes integers include positive and negative numbers.

Yes, EXCEPT for the number 0. It is a whole number but is not positive or negative. Real Numbers - Everything I. Rational Numbers- Any number except for non terminating decimals A. Integers- Any negative or positive number...not a decimal1. Whole Numbers- Any positive integer INCLUDING ZEROa. Natural Numbers- Any positive integer (NOT INCLUDING ZERO) The answer is not entirely correct, Whole numbers are numbers without a fractional part or decimal point. Therefore whole numbers can be negative as well as positive. -2 is a whole number but is not positive. There are a number of different interpretations for whole numbers, from non-negative integers, positive integers and all integers (which includes negative integers)

if they are both negative, add like they are positive numbers, but just add the negative sign.

The sum of two positive numbers is always positive.

Subtracting a positive number from a negative number is the same as adding two negative numbers, which is like adding two positive numbers except you're going to the left from zero on the number line instead of to the right. The rule is to add the absolute values (the numbers without the signs) of the two numbers and keep the negative sign. For example, -3 - 5 = (-3) + (-5) = -1 * (3 + 5) = -8.

Because it's redundant. If negative numbers are identified with a (-), then anything without it is unmistakably a positive number.

It is a negative connotation.

Any positive number is greater than zero. Negative numbers are less than zero. good answer but a positive number is a number without a - or the word negative in front of it

(-5)2 = 25. This is because multiplying two negative numbers together always leads to a positive number. Think about it like taking a negative amount of negative numbers, which switches them over to positive numbers. -52 = -25, because you are not multiplying negative 5 by negative 5, you are multiplying 5 by 5, and then multiplying that value by negative 1.

Positive and negative charges would have not effect on an object without charge.

Find the product of their absolute values (without regard for their signs) and then label the product positive. The process is exactly the same if both numbers are negative.

By subtracting any two of the numbers A-B , if the output number is negative , B IS GREAT and if its positive A is great

In Math, a negative can be represented with -. A positive can be represented with +, or just without a -.

You'll have to make some modifications to the "standard" radix sort. You can add on a set value to make all the numbers positive, then sort with radix sort, then subtract the value off all of them at the end. This probably isn't the best all-round solution because if your numbers get very large (and large negative numbers), you may be unable to add on the set value to make all your values positive without having the problem of overflow. In this case you'd have to make a division - a section of negative numbers, and a section of of positive numbers. Sort both of them using radix sort, then reverse the negative numbers section and put the lists together (remembering to sort out the minus signs before sorting the negative numbers).

-- write the difference between the numbers without regard for their signs -- give the difference the same sign as the original number with the greater size

Absolute value of any number is just the magnitude without any sign attached to it. For positive numbers the magnitude is the value of the number. For negative numbers just remove the negative sign and you will have the magnitude. In this case the magnitude is 7.61

9,8,7,6,5,4,3,2,1 without the decimaled numbers : ) that's all the real numbers or the positive numbers from 0 to 9., don't forget the decimals., 1.5., 2.5., 3/2., 5/2., etc are still positive numbers between 0 & 9.,

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

You get the difference between the sizes of the two numbers without regard for their sign, and the difference has the same sign as the larger of the two original numbers.
