How can you decide if the sum of two numbers is positive negative or zero without calculating the sum?
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.

How can you decide if the sum of two numbers is positive negative or zero without actually calculating the sum?
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.
How can you decide if the difference of two numbers is positive negative or zero without actually calculating the difference?
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.
What is greater than zero?
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
What does negative 5 in parantheses to the 2nd power equal and can you explain what it would mean without the parantheses is it the same thing?
(-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.
How is adding integers similar to adding whole numbers?
Integers include 0, the negative numbers without fractional parts, and the positive numbers without fractional parts. The "without fractional parts" part of the description implies that all of the integers are whole numbers. Therefore, if you are adding integers, you are adding whole numbers.
How do you decide if the difference of two numbers is positive negative zero without calculating the difference?
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.
Decide whether the sum will be positive or negative without actually calculating the sum -4+-12?
It will be negative thus -16

Without actually calculating the answer how can you decide if the difference of two numbers is positive negative or zero?
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.

Are negative numbers integers?
Integers can be negative or positive numbers providing that they are whole numbers without decimals or fractions.
How can you decided if the difference of two numbers is positive negative or zero without actually calculating the difference?
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.
Are all whole numbers positive 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)
How do you add negative integers without using the number line?
if they are both negative, add like they are positive numbers, but just add the negative sign.
Why don't you put a positive sign in front of a positive number?
Because it's redundant. If negative numbers are identified with a (-), then anything without it is unmistakably a positive number.
How do you subtract a positive by a negative?
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.
What is greater than zero?
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
