  38. Non-zero digits always count toward the number of significant figures; zeroes count except where they are only setting the scale.[14]

  49. When multiplying or dividing, the number of significant figures in the result is equal to the smallest number of significant figures in one of the operands.[18]
  50. The operand with the smallest number of significant figures is 4.3, so our answer should have 2 significant figures.[18]
