Tricky Maths Symbols
Math brain teasers require computations to solve.
Each symbol represents one and only one of the numbers from 19 inclusive.
All the terms are added except the last one, which is a multiplication # * $ = &$.
&$ is a double digit number.
Solve :
\ + > = &$
^ + % = &$
? + > + @ =&$
\ + ^ + & = &$
# + ? + ^ = &$
# MULTIPLIED by $ = &$
HintNeed to use a lot of logical thinking and deduction: For a start: if \ + > are the biggest numbers possible, 9 and 8, the &$ = 17
& is non zero so it must be 1
& = 1

Answer
To check your answer:
1 = &
2 = @
3 = #
4 = ?
5 = $
6 = \
7 = %
8= ^
9 = >
6 + 9 = 15
8 + 7 = 15
4 + 9 + 2 = 15
6 + 8 + 1 = 15
3 + 4 + 8 = 15
3*5 = 15
For a complete solution:
\ + > = &$
^ + % = &$
Starting with the sums with only two terms; because two terms added together can only have a maximum of (9+8)= 17 and the first digit of &$ is nonzero, so the minimum is 12
Therefore & is 1
# MULTIPLIED by $ = &$
something multiplied by something else must be between 17 and 11 (from above)
There are only a few combinations, but only one possibility here
2 * 6 = 12
2 * 7 = 14
2 * 8 = 16
3 * 4 = 12
3 * 5 = 15
The second multiplying term is equal to the second digit of the answer = 5
Therefore # is 3 and $ is 5
Filling in what's known:
\ + > = 15
^ + % = 15
? + > + @ = 15
\ + ^ + 1 = 15
3 + ? + ^ = 15
\ + > = 15
^ + % = 15
These symbols must be 6, 7, 8, 9 because otherwise a result of 15 can't be got.
They must be either 9 + 6 or 7 + 8 in some order.
\ + ^ + 1 = 15
\ + ^ = 14 they can't be 9 (because 5 is already known.)
So they must be 8 and 6 in some order.
That also means > and % must be 7 and 9 in some order.
? and @ must be 2 and 4 in some order (They are the only symbols left for the only two numbers), and ? + @ = 6
? + > + @ = 15
That means > must be 9
\ + > = 15
That means \ = 6
\ + ^ = 14
^ is equal to 8
and % = 7
Filling in what's known again:
6+ 9 = 15
8 + 7 = 15
? + 9 + @ = 15
6 + 8 + 1 = 15
3 + ? + 8 = 15
? must be 4
and therfore @ = 2
1 = &
2 = @
3 = #
4 = ?
5 = $
6 = \
7 = %
8= ^
9 = >
6 + 9 = 15
8 + 7 = 15
4 + 9 + 2 = 15
6 + 8 + 1 = 15
3 + 4 + 8 = 15
3*5 = 15
