Students should remember the multiplication table of 15 at their fingertips. There are great benefits to reading the table 15 times. Which includes greater confidence and better results in performing arithmetic calculations. A 15- table is a multiplication table that contains 15 multiplications by whole numbers. Before we start learning about it, we need to know what table

15 is read. It goes

15 ones are 15,

15 two’s are 30,

15 threes are 45,

15 fours are 60, and so on.

The 15 multiplication table is easy to read. This number is multiplied by 15 by all natural numbers, how we write it mathematically is 15 × 1 = 15. Similarly, 15 twos are 30. In mathematics, this is written as 15 × 2 = 30. Here 15 and 30 are multiples of 15.

### Tips for the Table of 15

Here is a little strategy for memorizing the table of 15. To learn this trick you need to know about your ones digit, tens digit, odd number and even number. The trick is that as a result, as we go down the table line one’s digit always follows a 5-0 pattern.

15 × 1 = 15

15 × 2 = 30

With the number ten in the result, two consecutive equals and two consecutive odd numbers follow.

15 × 1 = 15 (odd number in place of tens) 15 × 2 = 30 (odd number in tens) 15 × 3 = 45 (even number ten) 15 × 4 = 60 (even number ten)

### Worksheet On Table 15:

Example: Rina wants to give each of her 15 friends 5 chocolates. That is, one friend will get 5 chocolates. Using table 15, find out how many chocolates Miley has to buy?

**Solution:**

Total number of friends = 15 and friend 1 will get chocolate = 5

Thus, total amount of chocolate = 15 × 5 = 75.

Example: Using the table, check:

a) 15 times 8,

b) 15 times 7 minus 5, and

c) 6 times 6 and 15 times 7

**Solution:**

a) First, we will write 15 times 8 times mathematically.

Using a table of 15, we have 15 times 8 = = 15 × 8 = 120.

So 15 times 8 is 120.

b) First, we will write 15 times 7 minus 5 numbers.

Using table of 15, we have 15 times 7 subtract 5 = 15 × 7 – 5 = 105 – 5 = 100. Do you? So 15 times 7 minus 5 is 100.

c) First, statistically we will write 6 times 6 and 15 times 7.

Using table of 15, we have: 6 times 6 plus 15 times 7 = 6 × 6 + 15 × 7 = 36 + 105 = 141

So 6 times 6 plus 15 times 7 is 141.
