This is a queue of countries:

$Ireland, Guinea, Romania, Italy$

Values:

$Ireland = 7$
$Guinea = 15$
$Romania = 60$
$Italy = 87$

enter image description here

Try to answer following questions:

1) $Mali$ = ?
2) $Iran, rot. 90°$ = ?
3) $Bolivia, rot. 90°$ = ?
4) $Malta$ = ?
5) $Cameroon$ = ?
6) $Ukraine, rot. 90°$ = ?
7) $Ghana, rot. 90°$ = ?
8) $Bulgaria, rot. 90°$ = ?

Hint 1:

Symbols such as stars in flags are unimportant

Hint 2:

Make a queue with the flags of the countries, in the right order.

Hint 3:

Try to create new flags with the queue.

    $\begingroup$ So it is first color times second color plus third color. $\endgroup$

  • $\begingroup$ Yes, that's true ! $\endgroup$ Commented Jun 29, 2019 at 17:36
  • $\begingroup$ Are there three different shades of red here? And if it matters, in which direction are the rotations? $\endgroup$ Commented Jun 29, 2019 at 18:28
  • $\begingroup$ No there aren't different shades of red. The rotations can be in both directions, but if you have the right idea you will see it. $\endgroup$ Commented Jun 29, 2019 at 18:34

Making a queue of countries and finding the first appearance of each countries' flag, as well as @Duck's comment, i.e. first number times second number plus third (0 if no third number), I get:

  1. $Mali$, Green Yellow Red (Guinea's flag reversed) $9\times 2 + 3 = 21$

    enter image description here

  2. $Iran, rot. 90°$, Same as Italy, $87$

    enter image description here

  3. $Bolivia, rot. 90°$, Same as Guinea $15$

  4. $Malta$ = White and Red, no third color (Italy's flag) $9\times 6 + 0 = 54$
  5. $Cameroon$ = $9\times 4 + 8 = 44$
  6. $Ukraine, rot. 90°$ = $7\times 8 = 56$
  7. $Ghana, rot. 90°$ = $Guinea$
  8. $Bulgaria, rot. 90°$ = $9\times 9 + 4 = 85$
