MULTIPLICATION OF A NUMBER BY 13, 14, 15, 16, 17, 18 OR 19 <\/strong><\/p>\n

Just similar to 12, to multiply a number by 13, multiply the left side digit by 3 and add to the right side digit.<\/p>\n

Similarly, for 14 multiply by 4, for 15 by 5, for 16 by 6, for 17 by 7, for 18 by 8 and for 19 multiply by 9.<\/p>\n

For example.<\/p>\n
