What is the additive inverse of 78?
Two numbers that are the same distance from zero on the number line but are on opposite sides of zero are opposite numbers, or opposites. The opposite of a number is called its additive inverse. The opposite of 78 is -78.
What is the product of two numbers is zero?
One or both of the numbers must be zero.
Is the product of a non-zero number and its opposite zero?
The opposite (or inverse) of a number can be defined in a number of different ways. For example, the additive opposite of 4 is -4 but the multiplicative opposite of 4 is 1/4 or 0.25 Since the question concerns the product it would seem more appropriate to use the multiplicative opposite. Then, the product of a number and its opposite will be always 1. Incidentally, the product of a number and its additive opposite will be the negative square of the number. In neither case will it be zero.
What is algebraic numbers?
An algebraic number is one that is a root to a non-zero polynomial, in one variable, whose coefficients are rational numbers.Equivalently, if the polynomial is multiplied by the LCM of the coefficients, the coefficients of the polynomial will all be integers.
Why is a negative number less than a positive number?
A negative number is defined as a number that is less than zero. Positive numbers, on the other hand, are more than zero. You can see that positive numbers are greater than negative numbers because they are all above zero, which negative numbers are not.
