Intoduction To Decimals

Decimal comes from the Latin root decem, which means ten.  To understand decimal numbers you need to understand how ten forms the basis of our number system.

Think of a number line for a moment.  Draw little lines between 0 and 1 so that it is divided into ten tiny parts - tenths! These  tiny parts  are  valued at 0.1, 0.2, 0.3, 0.4, 0.5 all the way to 0.9.

See how the number line between 0 and 1 is divided into ten increments or parts.  Each of these ten parts is a tenth.

Now between  1 and 2, we would have 1.1, 1.2, 1.3 1.4 all the way to 1.9.
This same rule applies between any 2 numbers on a number line.
This is esential to understanding working with decimals.

Here is your first and key concept in decimals.
