When dealing with large numbers you will need to
be able to use a calculator. Regardless of what
you have been told by friends complex machines
are not needed!
You require only the four basic functions plus
the usual trigonometric ratios Sin, Cos, Tan and
their inverse functions.
Remember:
 When you are dealing with numbers NOT
based on ten, such as time, you cannot use your
calculator.
eg. 14hours 29mins  +  6hours 15mins
 14.29 + 6.15 !
In a case like this add the hours and minutes
seperately.
Now continue with the exercises on the next page

PRIME NUMBER
 is divisible by itself and one only. The first few prime
numbers are 2,3,5,7,11,13,17,...... Do not confuse Prime numbers with odd
numbers!
Other numbers may be expressed as
PRIME FACTORS
             eg: 24O = 2 X 12O
                     = 2 X 2 X 6O
                     = 2 X 2 X 2 X 3O
                     = 2 X 2 X 2 X 2 X 15
                 24O = 2 X 2 X 2 X 2 X 3 X 5
TEST FOR DIVISIBILITY
divide by 2 (if the units figure is even), divide
by 3 (where individual digits added together are divisible by 3) and divide
by 5 (if the units figure is either 5 or O).
             eg: 861 = 8 + 6 + 1
                     = 15
                     = 1 + 5
                     = 6  as this divides by 3 , 3 is a factor of 861

Questions
"Fractions"
Note1
Addition & Subtraction:
Add 1/4 and 1/2 in your head. Easy isnt it? But what did you do?
More than likely you changed the 1/2 into 2/4 and then added another 1/4
thus obtaining the answer 3/4. Try this method :-

1      1

 -   +  -

   4      2
That is multiply the 1/4 by 2/2 (which of course is one) and the 1/2 by 4/4
(which is also one) to change each fraction into eighths so that you can add
them together - you can only add fractions with the same denominator (ie
bottom number) thus:

2        4      6                  3
                   -    +   -   =  - which reduces to -
                   8        8      8                  4
This might seem a trivial example but try it with 1/3 + 1/5 by multiplying
the 1/3 by 5/5 and the 1/5 by 3/3 to change each fraction into fifteenths!
The answer, by the way, is 8/15
The same method applies to subtraction:
3   1
      2
   3     1
            6      5          1
- - -    =
-  -  -
     =     --  -  --     =   --
5   2
      2
   5     2
           1O     1O         1O

"Fractions1"
Note1
Multiplication & Division
Multiplication of fractions is easy. Simply multiply everything on the top
then put this over everything on the bottom multiplied together - for
example:-
         3   4   12   This of course could be reduced to 3/5 - it is easier
         - X - = --   to do the reduction before you multiply top &  bottom
         4   5   2O   by cancelling the fours.
Division is just as easy.
RULE: Turn the fraction you are dividing by
up-side down and change the sign to multiply!
Example:-
         3/4 divided by 4/5 is the same as 3/4 X 5/4
   then: 3   5   15
         - X - = --
         4   4   16
Mixed numbers must be changed to improper fractions first:
eg 2 1/2 divided by 1 3/7 isthe same as 3/2 divided by 1O/7
then  3      7     21   This can be changed back to a mixed number
      -  X  --  =  --   1 1/2O
      2     1O     2O
In general for problems involving more than one sign do multiplication and
division first followed by addition and subtraction.

lines very much like the coordinates you

If 21 books cost 14.21p how much would 35 cost ?
As both 21 and 35 have a common factor of 7 find the cost of 7 books:
21 cost 14.21
7 books cost 3.O3p (divide 21 by 3)
35 books cost 15.15p (multiply by 5)

Calculator -
algebraic logic ?
You must know how to use your calculator properly. Each calculation must be
carried out in order
                      Do  (  )  brackets first
                    then   x
   powers
                    next  X     multiplication & division
                    last  + -   addition and subtraction
Try using your calculator now. Feed in 10 - 3 x 2 without taking any notice
of the priorities given above. The correct answer should be:
                   10 - 3 x 2 =  10 - 6  =  4
If your answer was 14 then your calculator does not use algebraic logic and
you should take care and enter the calculation in the correct order!
Always check the question to see how many decimal places to write the answer
to. A result of, for instance, 3.23546789 km for a question on how far Fred
runs to school is silly. 3.235 would be much more sensible
