Mental
Arithmetic is a form of
calculation that does not involve use of
any physical or external
gadgets / instruments such as a calculator , paper , pencil
or a computer. It (calculations) is solely done by human
mind using mental power or performing
mathematical calculations mentally. According to
scientific studies and research mental abilities in
children must be developed by the age of 12.
1.
The mental calculation is defined as
calculation of number conception and the way of imaging the abacus calculation
in brain is called as the mental arithmetic by image of abacus.
2.
In recent years we have been discussing
and studying the mental arithmetic by image of abacus which is more
advantageous than other skills in the light of the result of examination.
3.
The mental arithmetic by image of abacus
means that we calculate on the abacus in our brain without seeing the Physical
ABACUS
What are the
objectives of mental arithmetic education?
·
Train and inculcate in
children the habit of careful deduction based on careful observation.
·
Train and inculcate in children
the habit of good memory and recall of data with maximum efficiency and
minimum possible effort
·
Train and inculcate in children
the habit of using multiple skills simultaneously with maximum efficiency and
minimum economy.
·
Train and inculcate in children
the importance of sound reasoning and original thinking.
·
Expand the children's mental
prowess and faculties and thus to uplift their morale.

What are the mental
arithmetic methods ?
Mental arithmetic is a skill that can be cultivated initially by adopting the pen or bead. In the pen method we use pen and paper to perform the calculation. In the bead method we use an imaginary abacus in our minds to calculate and arrive at the answer. UCMAS adopts the later method, using an abacus. We can use the bead method to perform addition, subtraction, multiplication, and division. The different methods of calculation can be divided into :
·
Dictation
This is also called "Mental arithmetic calculation through listening’ to the sum/problem ". Someone will read aloud the numbers and the listener will perform the calculation.
·
Observation
The person will use the numbers that he sees and imagines the numbers to be the beads on an abacus. He will use this imaginary abacus to perform the calculation.
·
Silent Dication
The person will dictate the number to himself silently and use an imaginary abacus to perform the calculation.  |
·
Mental arithmetic skill is an
inborn talent.
Some people think
that only intelligent people can master mental arithmetic. In actual fact, as
long as a person has learnt how to manipulate the beads in an abacus, it will
be easy for him to master mental arithmetic. Therefore, as long as someone
practices the lessons diligently, he/she can master this skill.
·
It takes
only a short time to master mental arithmetic.
Mental Calculation
·
The mental calculation is defined
as calculation of number conception and the way of imaging the abacus
manipulation / calculation in brain is called as the mental arithmetic by
image of abacus.
·
In recent years discussions were
on studying mental arithmetic by image of abacus, and the methodology is more
advantageous than other skills in the light of the result of examination.

The mental arithmetic by image of
abacus means that we calculate on the abacus in our brain without seeing the
Physical ABACUS
