finally, the actual message display block.
(sry i actually defined 3 blocks.)

• flash [message] for 0.5 seconds
displays the message for 0.3s and clears the speech bubble for 0.2s.
this makes the message appear to flash.

⬆️ countdown block.
loops 3 times. decreases by 1. period.

⬇️ random number display block.
accumulates the sum in the variable `correct answer`.

lemme explain the source code.
the main flow is:
1) counts down 3, 2, 1.
2) displays 10 numbers.
3) asks the user to enter the answer.

i defined 2 functions ("blocks").
• say countdown
• flash random numbers

I created a Mental Addition game.

To answer the sum of 10 numbers that are flashed very fast.
