Sum of two numbers is 5 and their difference is also 5what is the product of two numbers?
The numbers are zero and 5. Their product is zero.
Is the sum of the squares of two numbers equal to the square of the sum of the numbers?
Not unless at least one of the numbers is zero.
Can the sum of two rational numbers be zero?
Yes, it can.
What is two numbers a and -a whose sum is 0?
'a' can be any number whatsoever. The sum of +a and -a is always zero.
Two numbers whos sum is zero what is this called?
Additive inverses

Is it never always or sometimes the sum of two positive integers is zero?
The sum of two positive integers is never zero. The sum of two numbers a and b can only be zero if a=-b, or a=0 and b=0. Since 0 is not a positive integer, and a and b cannot both be positive integers if a=-b, then it is impossible for the sum of two positive integers to be zero. _______________________________________________________________ The above answer is correct. Here is another way to say it: An integer is any whole number including negative numbers, positive numbers and zero. However, a "positive integer" is a whole number greater than zero. The "sum of two positive integers" means you are adding two numbers greater than zero together. Therefore, the sum of two positive integers can never be a negative integer, and can never be zero. Example: 1 + 1 = 2
What two numbers whose sum is 15 and the product is 0?
Zero and 15.
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 many even two digit numbers are there where the sum of the digits is 5?
Zero.
