Have you tried Sudoku puzzles?


Hi Ziran,

Did some checking and found Web Sudoku. Tried a few of the easy ones. First one took me ~ 45 minutes, played one earlier today and did it in ~ 25 minutes. Was surprised to see that the average time for most people is ~ 5 minutes for the easy ones, I'll have to get some more practice in :)

I had looked at the link for Pic 2 and didn't see the error; well spotted, Chris S!

Hi Nevermorestr! Are you finally off the 12-hour shifts?

Hello there Chipper Q! LOL I was told when I was hired that my hours would be 7 to 3:30 but to expect to work until 5 or 6. I have yet to get off before 7 and this week I've been working 14 to 15.5 hours a day (one of the drivers fell off the back of a truck and fractured his arm and another driver is on vacation). I haven't seen my son awake since Sunday... :(

Using addition, subtraction,

Using addition, subtraction, multiplication or division make the numbers "1 2 3 4 5 6 7 8 9" equal 100. The numbers have to be resolved in the same chronological order from lesser to greater (1+2*3+4...)

I suddenly realized I mistook 100 for 10 :)
I will think it over again for a while.

@ Ziran: Would one have to use algebraic expressions "()" to make the numbers equal 100? With a straight forward (starting with 1 and working to 9) I come up with this:

1-2= negative 1,
negative 1*3= negative 3,
negative 3-4= negative 7,
negative 7+5= negative 2,
negative 2*6= negative 12,
negative 12+7= negative 5,
negative 5+8= 3,
3*9= 27

Or perhaps instead of 1-2= negative 1, then 2-1= 1 for example?

Message 64359 in response to message 64358

If you follow the laws of mathematics, 1-2*3-4+5*6+7+8*9=100
One should always calculate multiplication and division before doing addition and subtraction. If you want to make exceptions from this priority, then you have to use algebraic expressions "()"
Your example would look like this: (((1-2)*3-4+5)*6+7+8)*9=27
If you were looking for a solution that calculates it from left to right then this is your answer.
(((((((1+2)*3)+4)+5)*6)-7)+8)-9=100
