What is the result of 42 x 0 x 6?

  1. 0

  2. 6

  3. 252

  4. 7

The correct answer is: 0

The result of multiplying any number by zero is always zero. In this question, regardless of the values of 42 and 6, because zero is a factor in the multiplication (42 x 0 x 6), the entire expression evaluates to zero. This fundamental property of multiplication states that if one of the factors is zero, the product will also be zero. Hence, the correct answer is zero.
