The knowledge of the method of Subtracting whole numbers
with vertical presentation and borrow method
is a prerequisite here. Once you master Subtracting
whole numbers, the method described here,
is easy to follow.
But remember that, simple things need perfection
and perfection is not a simple thing.
Study the Example and solve the problems
given in exercise and check with the Answers.
The following note is made use of here.
putting any number of zeroes to the extreme right
side of the decimal part of a decimal number does
not change the value of the decimal number.
Get The Best Grades With the Least Amount of Effort
Here is a collection of proven tips, tools and techniques to turn you into a super-achiever - even if you've never thought of yourself as a "gifted" student.
The secrets will help you absorb, digest and remember large chunks of information quickly and easily so you get the best grades with the least amount of effort.
If you apply what you read from the above collection, you can achieve best grades without giving up your fun, such as TV, surfing the net, playing video games or going out with friends!
Step 1 : For the given decimals, to be added, Make the number of digits after the decimal point equal by putting zeroes to the extreme right side of the decimal part, if required.
Step 2 :
Write the smaller number under the larger in
column form in such a way that the decimal points
of both the decimals are in the same column and the
digits at the same place are in the same column.
Step 3 :
Subtract as in the case of whole numbers.
Step 4 :
In the difference, put the decimal point directly under the
decimal points of the given decimals.

These reports are created and stored in a secure section of the program, available exclusively to you, the parent. The section is accessed by a password that YOU create and use. No unauthorized users can access this information.
Solution to Example of subtracting Decimals : In the given two numbers, there are maximum three digits after the decimal point.
Make both the numbers, to have three digits after the decimal point by putting zeros to the extreme right side of the decimal part.
So, the given decimals become 215.400 and 69.845.
Let us write these decimal numbers one under the other (with the smaller one below the bigger one)in column form so that the decimal points of both the numbers are in the same column and the digits at the same place are in the same column.
See 0 in the thousandths' place is sriked off to become 10
0 in the Hundredths' place is sriked off to become 9
4 in the tenths' place is sriked off to become 13
5 in units' place is sriked off to become 14
1 in tens' place is sriked off to become 10
2 in hundreds' place is sriked off to become 1

Progressive Learning of Math : Subtracting Decimals
Recently, I have found a series of math curricula (Both Hard Copy and Digital Copy) developed by a Lady Teacher who taught everyone from Pre-K students to doctoral students and who is a Ph.D. in Mathematics Education.
This series is very different and advantageous over many of the traditional books available. These give students tools that other books do not. Other books just give practice. These teach students “tricks” and new ways to think.
These build a student’s new knowledge of concepts from their existing knowledge. These provide many pages of practice that gradually increases in difficulty and provide constant review.
These also provide teachers and parents with lessons on how to work with the child on the concepts.
The series is low to reasonably priced and include
