how do you do scientific notation?
Scientific notation is a way to deal with writing out very large or very small numbers.
Do you have any examples you are struggling with?
a new movie costs £320 million to make write this amount in scientific notation
okay, how would you write it normally - without the word million?
320 000 000
So what do you think the scientific notation would look like?
Spot on, so how many 0's are there?
thats what i need help with i don't understand how to write it out
okay so we could write:
What does equal?
10000000 i think
Does that make sense?
to see if i understand
can you maybe ask me a question
We're not quite there yet, but I will in a second
Scientists often prefer to use normalised scientific notation. So if the first number is greater than 1, but less than 10 - we add a decimal point, and add one to the exponent. So we get
Okay, let's give it a go. What is the scientific notation for ?
9.75 to the power of 6
Almost! We must not say "to the power of 6" because that would look like this , what we want (and what I think you mean) is
okay i think i understand
and we would say "9.75 times 10 to the power 6"
You might see it on the calculator shortened to this as well.
Why do you think scientific notation is useful?
because you don't need to write a large number with lots of zero's?
Yes, often scientists deal with huge numbers, like the distance from the earth to the sun. It is a lot easier to write it out in scientific notation in these cases. They also often round the number to only a few significant figures to keep things really short.
thankyou for helping me understand
No problem Maina
