Question

If 7*8@3=2 and 18@5*4=19 then 4*5@8*7 is​

Answer 1

Answer

$4*5@8*7=0$

Step-by-step explanation:

Examining the given expression $7$ $*$ $8$ $@$ $3=2$, by mere logic we infer that

$*=-$ and $@=+$,

$7-8+3=2$

Now apply the same to the next expression to check whether the assumption is correct or wrong.

Thus $18@5*4=18+5-4=19$. Hence our assumption is correct.

Therefore apply it to the expression we want to find out

$4*5@8*7=4-5+8-7=0$.

hence the answer
