One-half and two.
The numbers are 28 and 29.
No, they are not!
One or both of the numbers must be zero.
The numbers are zero and 5. Their product is zero.
For two numbers to be equidistant from zero, one must be the negative of the other. As one is the negative of the other, it is the additive inverse of that number. The sum of an number and its additive inverse is zero.
That is called Absolute Value
30 and 45
That happens when one of the numbers is a multiple of the other.
Anything times zero is zero.
No. The product of two negative numbers is positive.
4 and 9
If one or both numbers are zero, then the answer is zero;if the two numbers have the same sign, then the answer is positive;if the two numbers have different signs, then the answer is negative.Incidentally, this is true of all real numbers, not just rationals.
Rational numbers are numbers that can be written as the division of two integers where the divisor is not zero. Irrational numbers are numbers that are not rational.Irrational numbers, therefore, are numbers that can notbe written as the division of two integers where the divisor is not zero.
Yes, it can.
