DECIMAL$

                                                DECIMALS

decimal number, or just decimal, is any number written in decimal sign , although it is more commonly used to refer to numbers that have a fractional part separated from the tenths part with a decimal separator (e.g. 11.25).

IT IS A VERY EASY THING TO LEARN!




ADDING DECIMALS
To add decimals, follow these steps:
  1. Write down the numbers, one under the other, with the decimal points lined up.
  2. Put in zeros so the numbers have the same length (see below for why that is OK
  3. Then add using column addition, remembering to put the decimal point in the answer.

E.G

4.52
       +
8.58
SUBTRACTING DECIMALS
To subtract decimals, follow these steps:
  • Write down the two numbers, one under the other, with the decimal points lined up.
  • Add zeros so the numbers have the same length.
  • Then subtract normally, remembering to put the decimal point in the answer.

E.G

1.000 
         -
0.056
0.944

MULTIPLYING  DECIMALS 
Just follow these steps: Multiply normally, ignoring the decimal points. Then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined.

  1. Very creative of a explanation of decimals, if I scaled this 1-10 I would give you a 9.999.
