Multiple and sub-multiples of units

Question 1

Why are measurements written using the standard SI units sometimes inconvenient to write in full?

Answer 1

Sometimes a measurement, using standard SI unit, will give you a very large or very small number that is inconvenient to write in full.

Question 2

What is the system for writing large numbers in a shortened way?

Answer 2

Mathematicians have a system for writing large numbers in a shortened way called standard form.

Question 3

What does writing numbers in standard form involve?

Answer 3

This involves writing the value digits of the number as a number between 1 and 10, and then writing the number multiplied by the power of 10 to expand it back to the full number represented.

Question 4

What is another system used to reduce the problem of very long numerical measurements?

Answer 4

Another system to reduce the problem of very long numerical measurements uses a standard test of abbrieviations to cut down the numbers that need to be written.

Question 5

Give different multiple sizes, what they will be to the power of 10, the prefix + their prefix abbrieviation
