$The levels for 10 out of 10 Mental Arithmetic - hard

$This file may be edited by parents and teachers so that the 10 out of 10
$mental arithmetic package may be customised to exactly meet any child's needs.
$Take care if you do edit this file as the program may fail if you do not
$have all the required data in exactly the form shown.
$We suggest that you backup this file before you make any changes. You can
$then restore the original if you have problems.
$Lines commencing with $ are ignored.

$The command line dictates which way questions are presented.
$The fotmat of each question is either:

$Question style 1
$  (n,n) [signOption] (n,n)=(n,n)
$The brackets hold the lowest and highest possibilities of the number
$and the Option is the carry sprcification.
$i.e. [+c] is plus, with carry
$     [-]  is minus (carry doesn't matter)
$     [-nc] is minus with no carry
$     [*] is multiply
$     [/] is divide

$ for example,
$     (0,20)[+nc](0,20)=(0,20),(0,20)[-nc](0,20)=(0,20)
$gives the addition and subtraction facts to 20 ensuring there is no carry.


$Question style 2
$The advanced format is:-

$   (low,high,decimal)[sign](low,high,decimal)=ú(low,high,deciaml)
$e.g.
$  (2,25,?2)[*](0,25,0)=ú(2,25,?2)

$...will give questions like
$   ú2.00 * 5 = ú10.00

$The question mark before the decimal figure tells the program that
$the number can have any number of decimal places up to that value.
$If you omit the '?, you'll ONLY get numbers of that precicion.

$If you omit the 'ú' the numbers will not be formatted (i.e. trailing
$zeros will not be added etc.)

$    (2,25,2)[*](0,25,0)=(2,25,?2)
$...will give questions like
$    2.75 * 5 = 13.75

$If the question is to be an addition or subtraction the money format
$is slightly different:-

$    (2,25,?2)[+](0,25,0)=ú(2,25,?2)
$...will give questions like
$    ú2.75 + ú5.00 = ú13.75

$ Use,\ at the end of a line for continuation

$The next six command lines dictate the content of the six levels.

$Level 1
(6,12)[*](6,12)=(36,144)
$Level 2
(0,144)[/](6,12)=(0,12)
$Level 3
(0,9999)[+](0,9999)=(0,9999),(0,9999)[-](0,9999)=(0,9999)
$Level 4
(2,99,?2)[+](1,99,2)=ú(2,99,?2),(2,99,?2)[-](1,99,2)=ú(2,99,?2)
$Level 5
(2,25,2)[*](0,5,0)=ú(2,99,?2),(2,99,2)[/](2,5,0)=ú(2,25,?2)
$Level 6
(6,12)[*](6,12)=(6,144),(0,144)[/](6,12)=(0,12),(0,9999)[+](0,9999)=(0,9999),\
(0,9999)[-](0,9999)=(0,9999),(2,99,?2)[+](1,99,2)=ú(2,99,?2),\
(2,99,?2)[-](1,99,2)=ú(2,99,?2),(2,25,2)[*](0,5,0)=ú(2,99,?2),\
(2,99,2)[/](2,5,0)=ú(2,25,?2)
