this just was on the radio here Write the digits from 1 to 9 in a line. If you put a plus sign after the 2, a times sign after the 4, and plus signs after the 6 and 8, the line shows 12 + 34 x 56 + 78 + 9, which equals 2003. That's nine years off from our current year 2012. This example uses four arithmetic symbols. The object is to use just three of the following arithmetic operations: addition, subtraction, multiplication and division, in a line from 1 to 9 to get 2012 exactly. The operations should be performed in order from left to right. There are no tricks to this puzzle. Can you do it?

OpenStudy (amistre64):

OpenStudy (amistre64):

does the operations have to be different? or can you repeat operations?

OpenStudy (amistre64):

qtip in the ear tends to silence them too

OpenStudy (anonymous):

in the first example division is not used, i will guess that you can use two or even one

OpenStudy (amistre64):

3456 -789 ------ 2667 +12 ------- not 2012

OpenStudy (anonymous):

i am going to try it

OpenStudy (amistre64):

1+2345 6789 1+2345 ------- 2346 /6 ----- 391 +789 ------ 1180
