Introduction to how to learn multiplication fast:
Multiplication is one of the basic operations in mathematics. Multiplication can be done using math tables. Multiplying a small number is a simple task, using math table, but when we consider for a larger number, this process is tedious. We have introduced a lot of easy ways for multiplication to learn as fast as possible. Here we are going to see how to learn multiplication fastly.
Methods to learn multiplication fast:
Many new trends in mathematics are introduced how to learn multiplication fast. These fast methods save our computational processing time during multiplication of complex problems.
Here we use some of the fast ways to learn how to do multiplication effectively,
Methods to learn multiplication fast for two digit number less than 20:
While multiplying any two digit number that is less than 20, follow the following steps,
Let us consider, 12 * 14
Choose the largest number in the front.
Here the largest number is 14. Hence the sum becomes 14 * 12.
Add the largest number (14) with the last digit of the lowest number (2).
Hence it becomes 14 + 2 = 16.
Multiply 10 with the resulting answer.
Hence we get 16 * 10 = 160.
Now multiply the last terms of two given numbers.
Hence we get, 4 * 2 =8.
Add 160 + 8 = 168.
Thus we got the right answer as 168.
Thus we learn how to multiply fastly for two digit number less than 20.
Another example:
Let us consider, 15 * 17
Choose the largest number in the front.
Here the largest number is 17. Hence the sum becomes 17 * 15.
Add the largest number (17) with the last digit of the lowest number (5).
Hence it becomes 17 + 5 = 22.
Multiply 10 with the resulting answer.
Hence we get 22 * 10 = 220.
Now multiply the last terms of two given numbers.
Hence we get, 7 * 5 =35.
Add 220 + 35 = 255.
Thus we got the right answer as 255.
Methods to learn multiplication fast for any number with multiples of 9:
While multiplying for any number with multiples of 9, follow the following steps,
Let us consider, 64 *99
Take 64, add two zeros with 64, because we have two 9. (If three 9, add 3 zeros).
Hence it becomes 6400.
Now subtract 6400 with the original number 64.
Hence we get, 6400 – 64 = 6336.
Thus we got the right answer as 6336 in a fast way.
Another example:
Let us consider, 34 *99
Take 64, add two zeros with 34, because we have two 9. (If three 9, add 3 zeros).
Hence it becomes 3400.
Now subtract 3400 with the original number 34.
Hence we get , 3400 – 34 = 3366.
Thus we got the right answer as 3366 in a fast way.
Thus we learn how to multiply fastly any number with multiples of 9.
