修复错误：尝试在字符串上执行算术操作（加法）

if (hit.Name == "Base") then return end
   hit:BreakJoints()
   if (hit.Anchored == true) then hit.Anchored = false end
   wait(.5)
   for i=1, 10 do
        hit.Transparency = hit.Transparency + 0.1
        wait(0.2)
    end
    print("removing" + hit:GetFullName()) <---- 这里
    hit:remove()
end
connection = script.Parent.Touched:connect(onTouched)

但在第10行出现了"尝试在字符串上执行算术操作（加法）"的错误，请问能否修复这个错误？
