R + CAT + SHOE - RAT + SUN - CHOSE + MOON + I - NOON + GOAL + T - GOAT - U + E answer it, if u r super genius (this is only one word)

ANSWER:
R + cat = rcat
rcat + shoe = rcatshoe
rcatshoe - rat = cshoe
cshoe + sun = cshoesun
cshoesun - chose = sun
sun + moon = sunmoon
sunmoon + i = sunmooni
sunmooni - noon = sumi
sumi + goal = sumigoal
sumigoal + t = sumigoalt
sumigoalt - goat = sumil
sumil - u = smil
smil + e = smile! :)
