Prefixes are words attached to the front of other words to change their meaning. Metric prefixes are used with units of measurement to denote multiples and submultiples of units for easier counting of zeros. Scientific notation is a way of writing large or small numbers in a standard form by moving the decimal point and using an exponent, such as writing 0.00004 as 4x10^-5 where the decimal is moved left and the exponent is negative, or writing 1000 as 1x10^3 where the decimal is moved right and the exponent is positive.

2. WHAT DOES MEAN
BY PREFIXES?
A Prefix is a word attached to
the front of another word to
change its meaning.

4. WHY DO WE USE
METRIC PREFIXES
For Example If we are given a
number such that:
25000000000000 bytes.
Sometime we may not be
able to count the number of
zeros, so here prefixes are
used for easiness.
See Example (i)
USES EXAMPLE
Example(i):
25000000000000 bytes can be
written as:
25TB(Tera Bytes)
Example(ii):
0.000001 seconds can be
written as 1Us (Micro Seconds)

Scientific Notation is a way of

7. MEHTODOLOGY
In order to write a number
into the scientific Notation we
have to shift the decimal
point either on the right or left.
In case of right shifting of
decimal point the power on
the base will be negative i.e
0.00004 can be written in
Scientific notation as
4x10^-5
In case of left shifting of
decimal point the power on
the base will be positive i.e
1000 can be written in
Scientific notation as
1x10^3
