Significant figures in mixed operations

[elaine]

Oh my god THANK YOU. I knew significant figures were easy, but I had such a hard time applying sig fig rules to mixed operations. This really helped me understand what was happening and how to track my progress to come up with the right amount of sig figs in my answer. I can't thank you enough!

Watched several videos from other youtubers about how to do this, and your video was by far the easiest to understand! Thank you so much!

Thank you man. Your voice is so soothing I wish you were my professor. :)

[zedanorice]

[ktkco]

Thank you for clearly explaining how to track sig figs in mixed operations! I used to always go back and forth on what I was supposed to do and it made homework SO frustrating!

Awesome! Thank you! Teachers always seemed to skip this important part of mixing addition/subtraction and multiplication/division rules.

[MatthewRyanPrnka]

If you rounded the product of the first step calculation to an answer with no decimals/digits of precision. Then rounded the answer from the second calculation step of addition, the answer would be 25. But, you shouldn't round a calculation twice during a problem. The rounding is done in the final calculating step of the problem.

You are legit the most amazing Chemistry teacher ever!

[maskedmarvyl]

At 2:33, he writes a 13 under the 12, which may give the impression that he is rounding up during an intermediate step. I'm sure that was not his intention.

You do not do any rounding during the solving of an equation. You only do that at the very end.

I really can not express how relieved am I thanks to you. THANK YOU VERY MUCH!!🙂

This is the first confusion that comes to my mind with every textbook and every teacher that explains "these are the rules for mult/div, and these are rules for add/sub. Got that everyone??" Oh yeah, sure that, makes sense, BUT WHAT ABOUT THE MORE COMMON CASE WHERE THEY ARE MIXED?? Nobody seems to explain this, and it shouldn't be that hard.
