Video Summary

Clara begins with the number 12 and applies a sequence of operations represented by arrows. The operations include multiplying by 4, by 2, and dividing by 2. Since division isn't commutative, rewriting division as multiplication by fractions helps simplify. Clara multiplies by 4 three times and by 1/4 three times, effectively canceling each other. Similarly, multiplying by 2 twice is canceled by multiplying by 1/2 three times, resulting in a net operation of multiplying by 1/2. Starting with 12 and multiplying by 1/2, Clara ends with 6. The final answer is 6, labeled as B.
