Place value is the value individual digit has in its location:
in order from higher to lower value, there is thousands, hundreds, tens, and
ones.
When you divide by 10, you are affecting (only once) every digit from its current
place value to the right.
For example 1000 divided by 10 = 100, you have relocated every digit to the
right, making the zero dissolve (or better yet, divided by a hidden and in this
case unusable comma).
Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.
