+
+This is the answer key for the [flipping bird quiz](/microbit/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 BBC micro:bit, 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/>
+
+![](/static/mb/lessons/flipping-bird-0.png)
+
+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 BBC micro:bit, shade in the LEDs that show the value being stored into  the **global variable**, `count`. Explain why that particular area is shaded.
+
+<br/>
+
+<br/>
+
+![](/static/mb/lessons/flipping-bird-1.png)
+
+The display will show `2` because the remainder of 12 divided by 5 is 2.
