Identical Numbers and Their Sums

The video tutorial explores the pattern that emerges when adding the same number twice, resulting in even numbers. It provides examples such as 7 + 7 = 14 and 12 + 12 = 24, illustrating that the sum of two identical numbers is always even. The video explains that even numbers can be divided into two equal groups, reinforcing the concept of evenness. This pattern is consistent regardless of the numbers used, as long as they are the same.

What is the result of adding 7 + 7?

• 15

• 12

• 13

• 14

Which of the following sums is not even?

• 7 + 7

• 12 + 12

• 9 + 9

• 5 + 5

What is the pattern observed when adding two identical numbers?

• The result is always a prime number

• The result is always even

• The result is always odd

• The result is always a multiple of 5

Why is the sum of two identical numbers always even?

• Because it can be divided into two equal groups

• Because it is always greater than 20

• Because it is always a prime number

• Because it is always a multiple of 3

How can the number 24 be split when it is the sum of two identical numbers?

• Into two groups of 6

• Into two groups of 10

• Into two groups of 12

• Into two groups of 8

If 16 is the sum of two identical numbers, what are those numbers?
