Tables from 15 to 20

Tables are used by people for years and evolved with time. It is believed it was used in ancient civilizations such as the Egyptians and Babylonians. Earlier clay tablets were used for calculations, and with time the tables were developed.

A times table is the list of numbers we get when multiplying a number by the whole numbers. Learning tables from 15 to 20 will help students in calculations involving large numbers.
 

Tables from 16 to 20 are used to solve problems that involve large numbers. The table starts with 16 × 1 = 16, 16 × 2 = 32, and so on. Learning tables is a great way to improve speed and solve problems faster.
 

Multiplication charts are like a map that show the results when the numbers are multiplied. It is helpful for finding the answer for multiplication quickly without using the calculator or doing math in your mind. You can refer to the below chart for finding the multiplication tables for 15 to 20.
 

Children try to find easy tricks to learn tables. Here, we will be discussing a few tricks to remember tables of 15 to 20.

• Understanding the patterns of the multiplication tables can help in remembering the tables easily. For example, table 15 ends with only two numbers, either 0 or 5.

Table 16 follows the pattern of 6, 2, 8, 4, 0 in units place.
Table 17 follows the pattern of 7, 4, 1, 8, 5, 2, 9, 6, 3, 0 in units place
Table 18 follows the pattern of 8, 6, 4, 2, 0 in units place 
Table 19 follows the pattern of 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 in units place
Table 20 adds 0 in the units place for table 2.

• Breaking numbers into smaller parts and multiplying can make calculations easier.For example, 16 × 3 = 48, you can break it as (10 × 3) + (6 × 3) =  30 + 18 = 48.

• Practice the multiplication tables in day-to-day activities in board games or flashcards.
   

• Multiplication Table - It is the list of numbers that has the product of a number with whole numbers. For example, 20 × 2 = 40.

• Square Number - When a number is multiplied by itself twice, it is called a square number. For example, 162  is 16 × 16 = 256.

• Patterns — A predictable sequence in a table that makes it easier to learn. For example, 10, 20, 30. 

• Multiplication: This is the mathematical operation where a number is repeatedly added. For example, 2 × 5 = 2 + 2 + 2 + 2 +2 =10

• Whole numbers: All the positive numbers from 0 to infinity except decimals, fractions, and negative numbers are called whole numbers. For example, 0, 1, 2, 3, 4, ….
