No matter how far I've roamed, I've never found anything quite as perplexing as this puzzle. Perhaps you can help me find the missing numeral in the last line.
EXIT + LAX = 71
BROCCOLI + MASSIVE = 1255
SCANDAL + CLIENT = 601
DELIGHT + EMULSIVE = 1605
ADVISE + NAVY = 511
SIX + CANDLE = 459
DECEIT + DECEIVE = 1205
MEDIA + ALIVE = ?
Suggestions for improvement welcome
