**How to perform them:**

Count the vowels in the names of the directions of the flags.

Delete any curves, then rotate 180°.

Fill in every dot that's a proper divisor of the number (using the standard numbering).

Hold flags in the positions of the digits, where 1=south, 2=southwest, ..., 8=southeast.

Let A, B, and C be the numbers of all lines, dots, and diagonal lines. Write A×B, A×C, and B×C.

Make the background yellow, then cut the image in half.

Multiply by two.

Replace each row as follows: ⚬•s becomes Is, •⚬s becomes Vs, ••s becomes Xs. Delete ⚬⚬s.

Replace the first two letters with L and make the rest lowercase.

Replace the middle digit with ., increment the last digit, then write the name of that MacOS.

Write 1 [first digit] times, then 0 [second digit] times, then 1 [third digit] times.

Write a dot for each straight line, then a dash for each curve.

Write the largest prime factor, but backwards.

Write the number of occurrences of the most frequent letter, then the number of distinct letters.
