Below are some sample problems which MAY be helpful in preparing for the test.
Sample problem #1
You are given a seven digit number
Example:
1126345
1 = add
2 = subtract
The first digit tells the function (add, subtract, multiply, divide)
The second digit is the horizontal length
The third digit is the vertical length
The fourth digit is the row number for the first value
The fifth digit is the column number for the first value
The sixth digit is the column number for the second value
The seventh digit is the row number for the second value

Length = 1
#=2
Length = 2
# = 53
Thus 2 + 53 = 55
Red = column/Row number
Black = value

Example #2:
24 3 7 7 2 3
Since there is no row or column 7, subtract 6 for row,
SLLRCCR
or 5 for column
Operation = 2 (Subtract)
1st # Row = 1 (7 - 6) Column = 2 Length = 4
5738
nd
2 # Row = 3
Column = 2 (7 - 5) Length = 3
