Thank you so much half of my final math exam was about adding and subtracting scientific notation and before this I only knew multiplication and dividing them

Thank you so much! I kind of flunked my math test and you’re helping a lot so I can get a better score on my retake.

Same case when you're adding 2 scientific notations and one has a negative exponent?

[kunalmehta]

aren't we supposed to round off the last answers after calculations i.e to the least number of digits after the decimal place as per addition rule??

I do not understand which to choose? I understand the exponents have to be made to be the same - but how do you know which to choose?

[mahadsidhu]

I am not understand last 2 question exponent are -8 and -5 and then exponent are subtruct why we move right ???

One way works out with one less step than the other way I noticed.

Great, but sound effects get reaaly annoying when you're trying to understand.
