Question

If 9999 = 4, 8888 = 8, 1816 = 6, 1212 = 0, then 1919 =?

Answer 1

9,т.к оканчивается на 9

Answer 2

To decipher the pattern in the given equations, let's examine the digits in each number and see if we can find any correlation between the input and the corresponding output:

1. 9999 = 4
2. 8888 = 8
3. 1816 = 6
4. 1212 = 0

One possible pattern that emerges is the following:

1. The first digit of the input number is multiplied by the second digit.
2. The third digit of the input number is multiplied by the fourth digit.

Let's apply this pattern to the number 1919:

1. First digit (1) * Second digit (9) = 1 * 9 = 9
2. Third digit (1) * Fourth digit (9) = 1 * 9 = 9

So, based on the pattern, 1919 would equal 99.
