How can you determine when the sum of two numbers will be negative?

Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

Is the sum of two negative numbers is always negative?

Correct answer: The sum of two negative numbers is always negative, hence, this is the right choice. As for the other choices: The product or quotient of two negative numbers is always positive.

What is the product of two non negative numbers?

If two of the numbers are non-negative, then their product is non-negative. If there are no two non-negative numbers, then there are at least two negative numbers, and their product is non-negative. Of course, this holds for any set of three or more real numbers.

What is the sum of two negative numbers is always?

The sum of two negative integers is always a negative integer. Negative numbers: When we add two negative numbers, the result will always be a negative number.

Which statement best describes the sum of two negative numbers?

Sum of negative numbers is always negative.

How do you know if the sum is positive or negative?

Once you have the numerical answer, then you can apply a very simple rule to determine the sign of the answer:

• When the signs of the two numbers are the same, the answer will be positive.
• When the signs of the two numbers are different, the answer will be negative.

What is a non-negative number?

A non negative integer is an integer that that is either positive or zero. It’s the union of the natural numbers and the number zero. Sometimes it is referred to as Z*, and it can be defined as the as the set {0,1,2,3,…,}.

What’s a non-negative?

The term “non-negative” is used to account for situations that carry the same consequences as a positive result, even if a positive result was not received. One example is if a driver is directed to take a random drug test but refuses to do so.

Which is true about the sum of two negative integers *?

Therefore, the sum of two negative integers is always a negative integer.

Can the sum of two negative numbers ever be positive defend your answer with at least one example and a written explanation that describes money and debts?

Explanation: No, the sum of two negative numbers can never be positive. Adding two negative numbers means go DOWN the number line and then DOWN again.

How do you find two elements whose sum is closest to zero?

Two elements whose sum is closest to zero 1 Sort all the elements of the input array using their absolute values. 2 Check absolute sum of arr [i-1] and arr [i] if their absolute sum is less than min update min with their absolute… 3 Use two variables to store the index of the elements. More

Is the sum of two odd numbers always an even number?

Prove: The Sum of Two Odd Numbers is an Even Number We want to show that if we add two odd numbers, the sum is always an even number. Before we even write the actual proof, we need to convince ourselves that the given statement has some truth to it. We can test the statement with a few examples.

Is it possible to prove a statement with infinitely many examples?

However, by simply providing infinitely many examples do not constitute proof. It is impossible to list all possible cases. Instead, we need to show that the statement holds true for ALL possible cases. The only way to achieve that is to express an odd number in its general form.

How do you find the minimum sum of an array?

For each element, find the sum of it with every other element in the array and compare sums. Finally, return the minimum sum. 1) Sort all the elements of the input array. 2) Use two index variables l and r to traverse from left and right ends respectively. Initialize l as 0 and r as n-1.
