Align the decimal points and add them up; any gap at the end of a line can be filled with zeros if this makes the addition easier:
eg: 0.1 + 0.02 + 0.0003
0.1
0.02
0.0003 +
---------
0.1203
or
0.1000
0.0200
0.0003 +
---------
0.1203
Explain write ing decimals in Standard Form = (In number format like this... EXAMPLE: Two and two tenths is, (IN STANDARD FORM : 2.2) !
Standard form: 1.5*10-1 seconds, expanded form: (0.1 + 0.05) seconds.
1357 is in expanded form. In scientific notation or standard form it would be 1.357 x 103.
In standard form it is 6.235*10^1.In expanded form it is 60 + 2 + 0.3 + 0.05
standard form: .3 expanded form .3 its the same because there is only one place value being used

In standard form it is 1*10^1.
Because the basis for expansion are the powers of ten - exactly the same as in the standard form.
expanded form for the decimals 1.203 = 1 + 0.2 + 0.003
Standard form: 1.5*10-1 seconds, expanded form: (0.1 + 0.05) seconds.
.4 (0.4) in standard form is: 0.4 In expanded form: 0.4 = (0 x 1) . (4/10)
Eight tenths in standard form and expanded form = 0.8 or (0 x 1) + (8/10)
