When I discussed
with many 10th standard students who find mathematics
very difficult; I realized why mathematics was easy for me. The difference
is that when I was a 4th standard student most
of my classmates were able to tell instantly; 29 x 9 = 261. However, these
students who find mathematics hard cannot tell immediately 9 x 9 = 81 or even 9
+ 7 = 16. Negligence to master the number
operations such as addition, subtraction, division, multiplication at the
proper time i.e. the primary school level is the main cause of poor performance
of a student at the high school. One should be conversant with these operations
and multiplication tables.
Everybody cannot be a
mathematics wizard; but can use his ability to the maximum extent. Not only for
the competitive examinations, but in general this quality is essential, even
for the day to day study. This requires practice from the childhood.
Availability of computers, electronic calculators, mobile phones and
calculators therein is making many students unaware of the fact that these
things are to be done mentally and that too at the greatest speed.
Primary and middle
school days are the best to develop this ability. If you missed the days, you
can do it at any advanced stage. It requires awareness. Once you decide, you
can put some hard work. Repeated reading of the tables of multiplication from
two ones are two to thirty tens are three hundred; squares up to 30; cubes up
to 10; about 110 one digit additions and 55 one digit subtractions and 55
subtractions of one digit from the two digit numbers; such as 10 to 18.
Additionally, practice of solving exercises is a must. Don’t forget to do it
mentally.
There is no
alternative to above things. It’s easy, provided you are determined to do it.
Short cuts in arithmetic may be under different names such as Vedic mathematics,
Abacus are additional; and will not help as alternative to the primary study of
addition, subtraction, division, multiplication and multiplication tables.
For
convenience, I reproduce the above mentioned tables, and few practice exercises
in the following posts. Learn and practice with patience. These things look
easy, but need a great devotion and ambition to learn by heart. It’s not the
Aladdin’s lamp. If you are a beginner, it may require months’ devotion,
repeated reading, recollection and practice of solving addition, subtraction,
and division and multiplication exercises. One day you will find mathematics easy
and interesting.
