Tables 2 to 20

Introduction

Tables 2 to 20 make multiplication a breeze and improve your problem-solving skills. Even with the advent of calculators, remembering the multiplication tables from 2 to 20 remains a very effective technique. As a result, if you want to lessen your tension when doing multiplication, fractions, ratios, and division calculations, you must identify the numbers in the multiplication tables. So, here's a solution for you.

You will study multiplication tables from 2 to 20 in this mini-lesson. In addition to these multiplication tables, you will be given a variety of techniques and tactics for fast and simple computations.

1. Tables From 2 To 5

2. Tables From 6 To 10

3. Tables From 11 To 15

4. Tables From 16 To 20

5. Solved Examples

1. Observe all the tables from 2 to 20

a) Evaluate 3 times 9

b) The product of 12 and 8

Solution:

a) First, we will observe all the tables from 2 to 20 and write 3 times 9 mathematically as, 3 times 9 =

\begin{equation}

3 \times 9 = 27

\end{equation}

Hence, we get 3 times 9 as 27.

b) First, we will write the mathematical product of 12 and 8. Using the 12 times table, the product of 12 and 8 =

\begin{equation}

12 \times 8 = 96

\end{equation}

Hence, the product of 12 and 8 as per Tables 2 to 20 is 96.

2. Observe all the odd numbers' tables from 2 to 20 and evaluate the following: Check whether the result is also an odd number or an even one.

• 11 times 9

• 3 times 7

• 13 times 3

• 13 times 4 times 6

Solution: Even numbers can be split into two equal pieces, however, odd numbers cannot be divided into two equal parts. 3, 5, 7, 9, 11, 13, 15,... are examples of odd numbers. Even numbers include 2, 4, 6, 8, 10, 12, 14,...

a) In maths, 11 times 9 = 11 × 9

According to the 11-times table,

\begin{equation}

11 \times 9 = 99

\end{equation}

(an odd number).

b) In maths, 3 times 7 = 3 × 7

According to 3 times table,

\begin{equation}

3 \times 7 = 21

\end{equation}

(an odd number).

c) In maths, 13 times 3 = 13 × 3

According to the 13 times table,

\begin{equation}

13 \times 3 = 39

\end{equation}

(an odd number) .

d) In maths, 13 times 4 times 6 = 13 × 4 × 6

According to the 13 times table, 3 times table and 6 times table,

\begin{equation}

13 \times 4 \times 6 = 312

\end{equation}

(an even number).

3. Observe all the tables from 2 to 20

a) Evaluate 16 times 8

b) The product of 8 and 8

Solution:

a) First, we will observe all the tables from 2 to 20 and write 16 times 8 mathematically as, 16 times 8 =

\begin{equation}

16 \times 8 = 128

\end{equation}

Hence, we get 16 times 8 as 128.

b) First, we will write the product mathematically. Using the 8 times table, the product of 8 and 8 =

\begin{equation}

8 \times 8 = 64

\end{equation}

Hence, the product of 8 and 8 as per Tables 2 to 20 is 64.
