Multiplication tables are fundamental to learning maths. A student needs to learn them by heart in order to excel in maths. Though it is difficult to remember and learn all the tables from 1 to 100 students can easily learn the multiplication tables 1 to 30 by using a few simple tricks. These multiplication tables improve the speed and accuracy of solving difficult mathematics problems.
The students can also use the calculator for carrying on the calculations. But, we do not encourage this as they are not allowed to use them in schools and examinations. Thus, if they use calculators while solving the maths problems at home, they face difficulty and take more time while solving the questions in examinations.
Also, the use of the calculator prevents mental skills to grow in children. It also increases their dependency on calculators rather than on their minds.
The students can learn and memorize the tables in three simple ways, viz, visualising, reciting and writing them. The visualization helps in memorizing the multiplication tables easily. Practising the tables by continuous recitation and writing is the best way to learn them by heart.
Ease in Calculations:
As the students move towards the higher classes i.e. from primary to secondary, solving the problems quickly and accurately becomes extremely significant. The multiplication tables are not only useful in solving maths problems but also that of Physics. Say for example, while calculating the LCM of a given problem, the students need to know all the multiples of the given number.
However, when you need to multiply large numbers say beyond the table of 20, you will have to rely on the fundamental rule of multiplication. For example, we want to multiply 46 × 14. The first step is to multiply 6 and 4. The student needs to know that six fours are twenty-four. Next step is to multiply 4 and 4. Here again, he must be able to recall that four fours are sixteen. Thus, this is where the multiplication tables are useful and come handy for students.
Tables 2 to 30
Learning the multiplication tables from 1 to 20 acts as a base for solving the problems related to division, fractions, long multiplication, algebra and physics problems. For the students who do not memorize or learn these tables solving mathematics, problems become hard. We can use calculators for solving complex problems but using them for simple multiplications may involve more time. So, using tables is quicker.
As the students reach the higher classes, they need to learn the tables from 21 to 30 also. These tables are vital for quickly and accurately solving the tough problems. However, we may notice that some tables such as the table of 10, table of 11, table of 20 and table of 22 follow a pattern. This makes them easy to memorize.
The maths tables not only help us in solving maths problems but also in day-to-day life. For example, if you buy 5 packets of milk and the cost of each packet is Rs. 40 then you can easily calculate the amount to be paid to the shopkeeper with the use of tables. Simply, multiply 40 by 5 and you get the cost i.e. Rs. 200.
