How many significant digits should be reported in the answer to the following calculation (4.3-3.7) x 12.3?

To determine the number of significant digits in the result of the calculation ((4.3 - 3.7) \times 12.3), we first consider the operations involved. The subtraction (4.3 - 3.7) has two significant digits (because 4.3 and 3.7 each have two decimal places). The multiplication by 12.3, which has three significant digits, will be limited by the result of the subtraction. Therefore, the final answer should be reported with two significant digits.
