Math Symbols
You have the numbers 2 3 4 6 7 8 represented by the symbols # $ & % ? ! Each symbol represents one and only only number. From the following can you figure out which number matches which symbol? (X means multiplied by)
?# = # X !
?# = $ X %
#? = ! X &
$? = % X #
?# = # X !
?# = $ X %
#? = ! X &
$? = % X #
Answer
? 2$ 3
# 4
! 6
& 7
% 8
From the first two equations:
?# = # X !
?# = $ X %
You need to find the same product from four different numbers. And the second digit of the product (#) must be a factor
2 * 6 = 12 (2)
or
3 * 4 = 12
or 6*4 = 24 (4)
or
8*3 = 24
The 3rd equation is the opposite so its either 21 or 42
Which can only be made from 7*6 or 7*3
We could have
2 * 6 = 12
3 * 4 = 12
3 * 7 = 21
But then we have fail to use 8!
so we must have
24 = 6*4
24 = 8*3
42 = 7*6
so we know
? 2
# 4
so
! is 6
& is 7
3 and 8 can be got from:
$? = % X #

There are variations of this theme, and I have fun with all of them.
Ouch,
In the teaser, 3 is represented by *, but in the equations, you are using the $ symble. Fun though.
Small mistake, but still solvable
Fun!
Fun!
