Is the product of an irrational number and a rational number always equal an irrational number?
Yes, except in the degenerate case where the rational number is 0, in which case the product is also 0, a rational result.
What is a negative number times a negative number equal?
If the signs of both numbers are the same, the product will be positive. If the signs of the numbers are different, the product will be negative.
What does a rational number times an irrational number equal?
The product of 0 and an irrational is 0 (a rational), the product of a non-zero rational and any irrational is always irrational.
What is the product of any number and 0?
The product is obtained by multiplying two numbers. The product obtained by multiplying a number by 1 is equal to the number, i.e. 1 x 10 = 10(product). Therefore the product of any number and 0 is always 0.
Can the number of protons always equal the number of electrons in an atom?
This is not a general valid rule; ions have a different number of electrons.
In an atom the number of protons is always equal to the number of?
In a neutral atom, the number of protons is always equal to the number of electrons.
Is the number of neutrons equal to the atomic number?
In an atom, the number of protons is always similar to its atomic number. (The number of nutrons may be similar or different.)
What is the product of a fraction and its reciprocal is always equal to?
It is equal to 1, but not always: the reciprocal must be defined for the equality and the reciprocal is not always defined.
What does the atomic number always equal inside an atom?
Atomic number is always equal to the number of protons in an atom.
In an atom the proton always equals the number?
Yes, the amount of protons within the atom is always equal to its atomic number. If a proton is removed, you get a different element.
Does a number times 0 always 0?
Yes a number multiplied by zero will always equal zero if you talk about integers. If you talk about limits, it's different.
Dose a negative number plus a negative number equal a positive number?
No. The sum of two negative numbers will always be a negative number. If, however, you multiply the numbers, their product will be positive.
