# How do you use symbols to make the statement 9_45_9_8 = 49 true?

So for this I started with the operations done on 45 because I initially felt that it was the "outlier" among the values given. Note that you can start with any number that you are comfortable with.

[Trial-and-Error Portion] 9_45_9_8 = 49 9_45/9_8 = 49 9_5_8 = 49

[Continuation of Solution] 9_5_8 = 49 9_5*8 = 49 9_40 = 49 9+40 = 49

Luckily in one try we were able to reach the answer, but most of the time you would need to use trial and error to arrive at the right combination of operations.

*The explanation may be confusing but feel free to comment or post questions in the comment section if you think that the explanation needs more elaboration then I'll try to reply asap :D
