+i first solved it this morning using vim, since i had no idea how to use regex in uiua. this is how i did it in vim (with some regex help from (kagi assistant)[https://help.kagi.com/kagi/ai/assistant.html]):
+
+```
+:e "input"
+100J                                  # there are few lines, join them all
+:%s/\(mul(\d\+,\d\+)\)\|\(.\)/\1/g    # find all mul expressions
+:%s/mul(\(\d+\),\(\d+\))/\1*\2+/g     # replace all mul expressions with the operands multiplied together with a + appended
+$x                                    # remove last +
+:'<,'>s/.*/\=eval(submatch(0))        # evaluate the expression
+```
+
+my uiua solution is very similar
