Why does multiplying a whole number by 10 always add a zero to the right of the number?

That's a phenomenon that you notice after the fact. Try it out. Multiply any whole number by ten.
3 x 10 = 30
492 x 10 = 4920
It's the way the decimal system is structured.
Ten to the first power is ten.
Ten to the second power is one hundred.
Since multiplying a number by ten adds a zero, the reverse is true. Adding a zero to the back of a number multiplies it by ten.
