45.86 ''4' is in the 'tens' column '5' is in the 'units' column '5' is in the 'TENTHS' column '6' is in the 'HUNDREDTHS' column NB Note the use of '-ths' for the decimal digits.
It's because of the functions of the different columns, or positions in a number. Remember, we can express extremely large numbers, using only nine symbols. The columns mean something. The first column to the left of the decimal is the "units" column. For standard arithmatic in base ten, only the symbols 0 through 9 can go in this or any column. Start with the number 9, and add 1 to it. You now have 10, obviously. You no longer have anything in the "units" column, and you have 1 in the "tens" column. The number 23 has 3 "units", or "ones", and 2 "tens". If you add 7 to it, you see that 7 plus 3 equals 10. The number 10 can't all go in the "units" column. The one has to be added to the "tens" column, because that's what it is-- a "ten". It is this very same idea that comes into play when doing a multiplication.
'13' is '1' the tens column '3' is the units column .
The first 1 is in the units, or ones, column, so its value is one The second 1 is in the tenths column, so its value is one tenth (1/10).
Yes they must be in the same units of measurements.

The digit in the units column of the number 7157 is 7.
'13' is '1' the tens column '3' is the units column .
In order to subtract or add data you must make sure it has the same units.
The first 1 is in the units, or ones, column, so its value is one The second 1 is in the tenths column, so its value is one tenth (1/10).
The Standard form of the number 39000 is... 3.9 X 104. In standard form, the first significant figure is in the units column (in this case the 3), and the index (the little number) is the number of columns this first significant figure is away from the units column in the actual number. So in 39000, the 3 is four columns away from the unit column, which is why it is 104. Hope that cleared it up. :)
7.846 Hundredths column is '4' NB Tenths columns is '8' Thousandths column is '6' The units column is '7'
