3+4*5/6*7+8-9

Which expression will be solved first?

here * and / are of same hierachy, then the rule of associativity applies, this rule says, solve the operators in the order they come, when they are in same hierarchy.
this will be the solution

3+4*5/6*7+8-9
=3+20/6*7+8-9
=3+18*7+8-9
=3+126+8-9
=129+8-9
=137-9
=128
