About anything > Puzzle and task club 

Well i've decided to create a special topic where we could share about our knowledge:)
You could test your skills in math ;) post your puzzles and tasks in this topic:) lets try to solve them togather.
Club is for wiae people:) so turn on your brains ;D
Please dont flood this topic
Thank you for attention and have fun here!

So i've got 1st task here!
How can it be possiable:
20-18=92 How can it be possible?:) Waiting for your answers.

2nd task!!!
There are 10 fruit trees in garden and they grow in 5 lines (Dont know did i wrote it correctly:)) and in each line there are 4 fruit trees.... how can it be possible?:) waiting for answer here and/or a drawing in my e-mail !

up

DOWN

:P isn't there anyone smart?:)

noones interested

Isn't here any smart person?

up! :o

first task:
My guess is that u divide 20 in 10 and 10 and the 18 > 1 and 8... then u make 10 - 1 and 10 - 8... that's how u get 92, supposely, i know its wrong but it's the only way i can explain this

Simba boy you're almost right. It's easier to turn the 20 into Roman numerals.

Then it should look like:
XX
-18

X-I=9
X(10)-8=2
=>92

Second one is harder but more interesting. Try to solve it :)

This is stupid but i think since there are five lines and 4 fruits in each line then u put the lines toghter making 2.5 lines left and 4 times 2.5 is 10

How can you make 2.5 lines from 5? :o 5 lines. every line 5 fruit trees. ) It's easier if you create a drawing.

so ever line 5 fruits or 4... u've messed me up now

its like this every line has 4 fruit trees and there are 5 lines

5 divided by 2 is 2.5
2.5 times 4 is = to 10

Better draw it. 2.5 times? what does it mean?

If you don't solve I will publish the answer. )

i have it, i think... how should i draw?

Correct. :)

Two players are calling different numbers, which aren't greater than 10. The called numbers are summed up. Winner is the first one, who calls the number 100.

For example: The first player calls: 5. The second one says 7. So in total now it's 5+7=12. The winner is the player whose called number makes the final sum of 100.

The task is: Find out, what are the most important rules to win this game for any of the players, who is participating in the game. Of course you have to base your answer on mathematical explanations.

GL!
