The Numberblocks are at the starting line of the Numberblock Rally at the top of Mount Numberland. One shows up late before the race starts.
And they're off! Nine and One are going slowly. Ten is in the lead, but she trips on a rock.
10 - 1 = 9
Eight lays front-side-up on his car and races, his wheels replaced with his legs. Suddenly, his car's part come loose.
8 - 2 = 6
Six spins to the other direction while Eight chases her. Seven dodges them, but trips on another rock.
7 - 3 = 4
Six and Nine encounter a series of dips. Nine jumps over a dip.
9 - 3 = 6
Both Sixes jump over two dips.
6 - 3 = 3
6 - 3 = 3
Both Threes commentate and argue about it. However, the original Three, above the dips with the other Numberblocks, is in charge of the commentating and pushes the other Threes out of the way.
3 + 3 = 6
The two Threes kicked up a dust cloud that Nine enters, causing him to sneeze out a One, becoming Eight.
(9 - 1 = 8)
Eight speeds, but bumps into Three, sending them flying and crash-landing onto the other racers, blowing them up into a bunch of Ones. One continues racing while the nine remaining ride on her tail and into a mud puddle.
1 +1+1+1+1+1+1+1+1=9
In other words:
9×1=9
One finishes in first place! One is rewarded the Numberblock Rally trophy while the others cheer for her.
