Last Year: 2009 = 2134 - 56- 78 + 9
This Year: 2010 = 1978 + 6 x 5 + 2 x 3 - 4
Next Year: 2011 = 1978 + 6 x 5 + 2 + 4 - 3

(1 + 9) x (4 + 6) x (7 + 3) x 2 + 8 = 2008 [sorry I didn't use 5]"

(245x8) + 63 -9 -7 +1 = 2008"
Did this while the rest of my class were at the Royal Cornwall Show"
Solved by one of my Year 4 pupils"
34 x 56 + 98 + 7 -2 +1"
(6 + 4) x (7 + 3) = 100
20 x 100 = 2000 + 9 = 2009."
(9+1)x 8 x 5 x(2+3)+ 6 +7 -4 = 2009 (Tom Hatton)
Submitted by year 9 students at Bridgnorth High School."
( 987+16-3 )* 2 + 5 + 4
98 * 21 - 56 + 7 * ( 4 -3 )
218 * 9 + 45 + ( 6 - 7 ) + 3."
(6 + 4) x 5 x 2 x (3-1) + 9 - 7 + 8 = 2010."

Solved in seconds!!"
2009=96*8+7+1234
I did use a calculator."
My solution is ( 9 x 8 x 7 x 4 ) - 6 - 1 - 5 + 2 + 3 = 2009."
Good, achieved the results I required
Satisfactory
Didn't really capture the interest of the students
