Perform the following mathematical operation, and
report the answer to the
appropriate number of
significant figures.
15.67 - 6.943 = [?]

8.73

Explanation:

when you are adding or subtracting numbers, the sigfig (significant figure) is based on how many numbers after the decimal. with this info, we can see that 15.67 has 2 sigfigs and 6.943 has 3 sigfigs. when you subtract normally, you would get 8.727, which has 3 sigfigs, so you would round the last 7 up to get 8.73 with 2 sigfigs!

also it is to 2 sigfigs because we know that we go by the least number of sigfigs. hope this helped!

oh it is true if thats what you are asking

the right answer is c i just did the question.
