# flipping bird quiz answers use modulo with a conditional. This is the answer key for the [flipping bird quiz](/lessons/flipping-bird/quiz). ## 1. What does "modulo" mean in math? <br/> Modulo (or Mod) is the remainder of a division problem. ## 2. Consider the following code If the rectangle below represents the @boardname@, shade in the LEDs that show the value being stored into the **global variable**, `count`. Explain why that particular area is shaded. ``` count = 1 count_ = count_ + 2 ``` <br/> <br/>  The variable `count` is now equal to 3. <br/> ## 3. Consider the following directions Modulo (Mod) tells us what the remainder of a division is. For example, `15 mod 4 is 3` since 15 divided by 4 has a remainder of 3. ``` count = 12 count = math.mod(count, 5) ``` If the rectangle below represents the @boardname@, shade in the LEDs that show the value being stored into the **global variable**, `count`. Explain why that particular area is shaded. <br/> <br/>  The display will show `2` because the remainder of 12 divided by 5 is 2.
