Tables from 15 to 20
Tables help us to perform mathematical calculations which involve numbers. As multiplication tables are a part of basic math, they help solve problems quickly. Tables can be used in calculating costs, measuring areas, etc. In this topic, We can learn more about tables from 15 to 20.
Multiplication Tables 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 of 16 to 20
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 Chart 15 to 20
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.
Tips to memorise multiplication table of 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.
Common Mistakes and How to Avoid Them in Tables 15 to 20
Tables are the basics of many applications of math. Mistakes are common when kids are learning multiplication tables. Here are some common mistakes and the ways to avoid them to help in learning tables easily.
Mistake 1
Skipping the steps
Skipping the steps in between the breakdown method and directly writing the answer results in mistakes. To avoid it, students should be more careful when it comes to large numbers. For example, when multiplying 18 × 3, here 18 can be broken down into 10 and 8
So, 18 × 3 = (10 × 3) + (8 × 3)
= 30 + 24 = 54
Math Tables 15 to 20 Examples
Problem 1
Multiply 18 × 5 using the breakdown method
90
Explanation
To multiply 18 × 5, we can break 18 as 10 +8
So, 18 × 5 = (10× 5) + (8 × 5)
= 50 + 40
= 90
Therefore, the product of 18 and 5 is 90.
Problem 2
John buys 2 liters of milk every day. How many liters of milk does he buy in 19 days?
John will buy 38 liters of milk.
Explanation
To get the total liters of milk, multiply liters of milk per day × total number of days
Liters of milk bought per day = 2
Total number of days = 19
= 2 × 19
= 38
Problem 3
Paul gets $20 per hour for working. How much will he earn if he works for 8 hours?
Paul earns $160.
Explanation
Dollar per hour multiplied by the total hours to get the total amount
Dollar per hour = 20
Total hours = 8
20 × 8 = 160
Problem 4
A shop packs 16 juice bottles in a box. If you buy 9 boxes, how many juice bottles do you have?
144 juice bottles.
Explanation
Multiply juice bottles in a pack with the total number of boxes
= 16 × 9 = 144
Problem 5
A girl reads 15 pages of a book every day. How many pages did she read in 20 days?
She will read 300 pages.
Explanation
Multiply the pages with the number of days to find the total pages.
= 15 × 20 = 300
