I had to take a test on significant figures and failed twice. It was the first time that I have ever made a grade below a B. I tried to learn it myself and even asked people for help and still never understood the concepts. I was so frustrated, but I have to say your videos helped me to understand them a 100%!

@GuitarxxPro 112560 doesn't have 6 sig figs, because of the zero at the end. watch my video "significant figures and zeros (1.3)" and go from there--it deals with decimals and the sort of questions you need help with.

i don't understand your question. i'm taking 7000 and writing it in scientific notation, so the answer is 7.000 x 10^3. do you know how to use scientific notation? if not, i've got videos on that topic: "scientific notation introduction" and "scientific notation practices problems." message me if you're still confused after watching those videos.

In your first example What if the answer was suppose to be in one significant figure? Can you leave it at 7,000? And can you put it in scientific notation? If so, would it be 7x10^3 ?
@tejseth80277 жыл бұрын

@paigeelise54213 жыл бұрын
So in the second example you wanted the second number to be the number of significant figures but in the third example you wanted the first number to be the guide for sig figs....so my question is if you have two different amount of sig figs in two different numbers, which one do you use as a guide?

I guess it would be 4.567 x 10 ^3 Used the calculator to get the scientific number and this was the answer.

All the videos made sense until the decimal points were moved and there were fractions. Why did the points need to be moved and why did the problems in the end need to be written as fractions? I was a little lost on figuring how to do the fractions.

Yo! On the second problem. 1:49 , 112560 isn't a "5" significant figure, it's 6 i guess. =D By the way, why don't you release a tutorial about decimals and different significant figures? For example : 8.08 dm x 5.3200 dm = ? ( I am in a desperate need of this sort of tutorial-) _GxP.

why does he round the 9 when he has a 7 to the left. Isn't the 9 greater then that would mean that there is no need to round up?

@Hardstyle_Queen9 жыл бұрын
***** When did he even considered that? I thought its the same, & he's just changing it into different sig fig number, by rounding off according to the equation & using the least sig fig digits for final answer. He did mention that its only considered a sig fig, if there's a decimal & the zero must be on the right/after a non zero. In that case, 2000 doesn't have any decimal. Any zero that comes after a non-zero, without any decimal is not a sig fig. For zero on the left, even with decimal we know its NOT a sig fig, unless its sandwich between 2 non-zero(with or without decimal).

when you convert something into scientific notation, the number (the mantissa, LOL) must be MORE THAN 1 BUT LESS THAN 10. If he uses 10^2, the answer would be 70.00 x 10^2. The problem is the mantissa can't be 70.00, it has to be more than 1 and less than 10. Therefore the correct answer is 7.000 (which is a number more than 1 but less than 10) x 10^3.
@112287hihello11 жыл бұрын
In the first e.g. your answer was 7.000 X 10^3 why shouldnt it be 10^2 or 10^4?? samething in the next examples.

+Merlin Alfane I know how to recycle very well. I recycle every piece of paper I use. I maybe use 20 sheets of paper to make a video. When your teacher copies a 10 page test for 20 students, she's already used 10 *times* as much paper as this video, just in one class period, in one day.
