Sig Fig Rules: Adding, Subtracting, Multiplying, Dividing, Mixed Operations |Study Chemistry With Us

Study along with Melissa Lucy as I go over what you'll need to know about significant figures. We'll specifically go over all the rules for adding, subtracting, multiplying, dividing and what to do when multiple operations are in one problem. You'll need a piece of paper and a pencil ready because we will also do some practice problems to help you get ready for your next exam.

💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

You have absolutely saved my life, I’m taking chemistry online cause of COVID and this really helped

[@jamitty.augustine7565]

Thank you so much for these videos! Honestly, the absolute best at explaining Chemistry.

[@melissamaribel]

Yay!! So happy to hear you are doing so well 🎉

[@lukagray2451]

GIRLLLLLL!!!! this vid helped me soooooo MUCH!!! THANK YOU!!!❤❤❤😭😭😭🙏🙏🙏🙏

[@iMaGiNaTiOnWpAsSiOn]

I am going to be taking basic chemistry this spring. I have never taken a chem class and stumbled across your videos. I started watching your playlist that is listed as “start here.” If I go through this entire playlist, does this pretty much sum up what my basic chem class will consist of? Is there another playlist in addition to this that I need to watch?

[@perezfreddy90]

Hi thank you so much for these videos! I’m currently taking gen chem 1 as well and I was so confused on how you find out the amount of neutrons but you really helped break that down. The only thing that still messes me up are dig figs when you have a mixture of rules in one equation.

[@christandme1372]

I watched your video "Rounding and order of operations used in significant figures" because I needed to learn the rules about zeros. It was great!

[@traplabspr5413]

with your help I will get an A this semester

[@binasaur3221]

I honestly love you. I'm in COLLEGE and I needed this and ALL of your videos. Would you be willing to do any O-Chem videos?

[@jany908]

Thank you so much! Very helpful!

[@ezulufaithfrances4297]

Wish to be like you someday....your videos made me improve a lot in chemistry calculations.... .but am still struggling with the theory aspect of chemistry and graph interpretation

[@malavikapillai3766]

w teacher appreciate your efforts!!

[@nzo430]

Hey Melissa, I am currently having a problem of not understanding a lesson. The lesson is electricity and chemistry from Cambridge Igcse book. I hope you can explain it to me! Love you 💜💜💜

[@joshuaarellano2057]

I'm currently taking Analytical Chemistry and i have a hard time understanding the colligative properties of a solution. Please help me Melissa, our preliminary examination is fast approaching and still I can't understand well the topic

[@yos1227]

I am from india currently studying in class 12. I have some doubts in thermodynamics, so can you help me in clearing that. Is there any platform of your channel for doubt sessions?

[@donnaneville1124]

I'm following along but getting a different answer for question 2. 5110x21.20/(44.11+1.223) (44.11+1.223)=45.333 5110×21.20=108332 108332÷45.333=2389.694042

[@catcupid6063]

Americans are so lucky to use calculators at school, at asian schools its pretty much banned.

[@albertapaulraj4321]

If you print the study plan you'll know what it is. It's in the description box

There’s a mistake in the video (1201x0.3)+4.811 360.3+4.811 = 365.111 ????????

[@halextherrivero4385]

the number is 12.01, the decimal is super light but its there, I didnt see it either!

[@keepmewthestars]

The number is 12.01 not 1201. Maybe that'll help

[@manthemanmantheman6611]
