Clue 5
Missing addends — the last clue
The box should hold eight loops but we only see six. Let us find the missing number of loops.
First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!
Step 1 — solve these
2 + ___ = 13
9 + ___ = 18
7 + ___ = 11
3 + ___ = 10
1 + ___ = 9
5 + ___ = 17
7 + ___ = 17
6 + ___ = 8
9 + ___ = 12
4 + ___ = 9
5 + ___ = 6
Step 2 — cross out the sentence with each answer
1.The villain speeds through the loop-de-loop, then takes a piece of orange track.
2.The villain rides along the playroom wall, then grabs a blue booster to zoom away.
3.The villain rides along the playroom wall, then hides a golden wrench in their pocket.
4.The villain flies off the mega jump, then snatches a green launcher from the floor.
5.The villain uses a quick speed boost, then snatches a green launcher from the floor.
6.The villain speeds through the loop-de-loop, then snatches a green launcher from the floor.
7.The villain drifts around the sharp corner, then grabs a blue booster to zoom away.
8.The villain flies off the mega jump, then grabs a blue booster to zoom away.
9.The villain drifts around the sharp corner, then takes a piece of orange track.
10.The villain flies off the mega jump, then hides a golden wrench in their pocket.
11.The villain rides along the playroom wall, then snatches a green launcher from the floor.
12.The villain speeds through the loop-de-loop, then sets a speed timer on the track.
