@yeedust watch my video on "scientific notation: multiplication and division." learn how to do that. then come back to this video and use significant figures in your calculation. your problem is no different from the ones i talk about in this lesson. use the significant figures rules to round.
@tdewitt451
@tdewitt451 12 жыл бұрын
you want there to be the same number of sig figs in both numbers because you're thinking about the rules for multiplication and division. but the rules are very different for addition and subtraction. in this case, you don't care about how many sig figs in the starting numbers, only where the decimal place is. if this confuses you, you should watch my video called "add and subtract with significant figures (1.6)"

Thank you for making this!

because i'm adding here, and there are different rules for addition/subtraction than there are for multiplication/division. you want there to be 1 sig fig because those are the multiplication rules. but this is very important--make sure to learn the addition/subtraction rules and it will make sense: watch my video called "add and subtract with significant figures."

no. look at the numbers we start with : 2 sig figs in 2.0, and 4 sig figs in 8.330. we round the final answer to the smallest of these, so it should have 2 sig figs. why do you think there should be 3 sig figs in the final answer?

Well, if you are from other country or you have no money to go to college and it will take a long time to get in this class again of course you will forget!! A lot of professors should be patient and be like you. Also, some other brain just does not like math so why push and rush?? Keep up the good work professor!!

I was so scared because I suck when it come to scientific notation (well at lease I use to) but then I found your video and that changed everything.

Two memory aids for adjusting the exponent of the 10. Case 1: up. "It was LEFT UP to me to clean the cat barf." (moving the decimal place to the left means increase, i.e., up, the exponent on the 10. Case 2: down. "The fire hall is right down the street from me." Moving the decimal point to the right means you decrease the value of the exponent on the 10.
