    What about zeros after the decimal point but have counting numbers after? Like, 0.001?

  • Liam Nork 4 years ago

    I cannot thank this guy enough

  • firdaus khan 4 years ago

    When u r telling they are non zeros then y are u even counting zero as a significant. Non zero means without zero doesn’t it..? then y is it being counted with other significants……?

    I need some help how many significant figures in 0.01210

    • Explain It to Me 4 years ago

      There are 4 significant figures. Only the 1210 of 0.01210 are significant. Zeroes before other non-zero digits are not significant.

    According to my Chemistry book, 83,000 would be “ambiguous”. Please explain why you say 2 significant figures.

  • Victoria Sansone 3 years ago

    Silly question in 83,000 isn’t it really 83,000.?

    Hey guys I got a nice trick to help with sig figs

    Imagine the number as a country of USA. Pacific on the left, Atlantic on the right.
    Then ask yourself, is the decimal Present, or Absent?

    If the decimal is (P)resented, then go to the (P)acific side, read from left to right until you hit a non-zero number, and then count.

    If the decimal is (A)bsent, then go to the (A)tlantic side, read from right to left until you hit a non-zero number, then count.

    Decimal itself is not considered to be part of sig fig counting.

    This video is 8 years ago. I am watching mostly your videos because I am preparing for my dream university entrance exam. Your cheerfulness and excitement when teaching is contributing a lot to my revisions because it makes me less anxious and helps me think positively. Thank you, mister, for what you do. God bless you.

  • kimberly 3 years ago

    bro these videos make it so easy!!!😭

  • Jacob Boldwin 3 years ago

    ONLY include ZEROS …

    “sandwiched” between non zero numbers
    AND
    zeros connected with decimal point by other zeros

  • AstroAaadhav 3 years ago

    Very very very helpful… Thanks a lot and keep making great videos like this…

    PERFECTION

  • Alfredo Ramos Quixan 3 years ago

    My professor only gave us the lab manual and he started using his computer. When I am liked, HELP… he comes and asks what I need help with, I tell him and he was like, “I want you to figure it out by yourself but also you can ask your classmates. Then he goes back into his computer.

  • Hackerman1969 3 years ago

    If you still check your notifications pls answer me this (I know I’m years late haha) but what does it matter that these figures are significant. If you remove zeros after the decimal then isn’t that changing the value completely? In my book it asks that I use 2 significant figures to represent given numbers. How is it possible to express 1.007 with 2 significant figures?

  • Aryan Saeedi 3 years ago

    you are so good thank you for being my best teacher ever :((((

  • Wolfster Ro3 3 years ago

    If it’s 0.32109, then there’s six dog figs just in case anybody was wondering

  • Wolfster Ro3 3 years ago

    The zeros after the decimal point are called trailing zeros, ex:834.000, the zeroes after the decimal point are trailing the sig fig numbers(834)

    Wouldn’t you keep the first 0 before the decimal point though in the 0.00062 one or whatever? Because otherwise the answer would just be 62?
