For number 1, the unit should be m³. Hope the video helps. If you haven't already, SUBSCRIBE!

8:20 sir , I m confused how it is 11.35 , shouldn't it be 11.4 . kindly solve my query :)

[@EHbhuiyan]

Don't round until the very end answer. Just keep track of significant figures. If you notice that I underlined the 3. If the problem was only adding, it would be 11.4. However, the next step involves multiplying. So, you don't round until after you finish multiplying.

I have a doubt...what if we multiply the numbers having same S F. Eg: 345 x 123 = 42435 for this how i have write final answer

[@youtube.schizo2393]

Ur ans is the first three digits

[@iloveyou.exehasstoppedwork2558]

It will be 42400
Write the first required digits starting from the left ( in this case the first 3 digits which are 424 )
Then look at the digit that is after the last required digit , if it’s from 0 to 4 then that final required digit will stay as it is
And if it was from 5 to 9 , you will add one to that final required digit
and finally
change the remain digits that are after the required digits to zeros

thankewww it was really helpful

[@shree3849]

Where are you from

[@medrizzstudy]

Sir for the unit of measure in number 1 it should be m³.

[@EHbhuiyan]

Yes. Someone else also caught the mistake in an earlier comment. I incorporated that into my pinned comment. Sorry about that.

[@medrizzstudy]

@@EHbhuiyan Correct

[@jonathannava9203]

Just a correction for the unit of measure in number 1. I believe it should be m³.

[@EHbhuiyan]

Didn't see that. Good catch.

[@afzalbadshahbadshah7942]

Sir there is ambiguity 11.35 has 4 significant figures because all non zero digits Ara all significant

[@EHbhuiyan]

At 8:11? The product SHOULD have 3 significant figures. HOWEVER, You don't round until the very end, and therefore you have to keep all digits in 11.35, which has 4 significant figures. Keep track of the significant figures as you go (purpose of the underline) but round at the very end. Hope that answers your question.

[@Yi-cz9mj]

OH

[@bhattshowkatfcc]

3.2×3.2

[@fixon1942]

on 5:45 how is it 30,000?

[@irfanfani8806]

because we need the answer with only one significant figure.
30000 has only 1 significant figure
rule: zeros on the right sides are not significant figures.

[@hypefuse4656]

number 5 is wrong 11.35 is not 3 sf

[@EHbhuiyan]

Rules are different for adding/subtracting sig figs. Here's my video on how to add/subtract with sig figs: ua-cam.com/video/0DjNtiyT6zc/v-deo.html
Also, you shouldn't round until the very end. Just keep track of sig figs.

Thank you so much I didn’t understand bc my teacher goes at a very fast pace🥲 very thankful for this video
