The math topic involves practicing prime factorization using factor trees where some factors are missing. Each problem requires determining the missing factors that, when multiplied together, give the number directly above them. This topic forms part of an introductory unit on factoring and primes. It includes a series of exercises to help develop understanding and skills in breaking down composite numbers into their prime factors using a structured visual method.
