<svg
   xmlns="http://www.w3.org/2000/svg"
   version="1.1">
    <path
       style="fill:#000000;fill-opacity:1"
       id="diff"
       d="M 49,38 C 48,47 72,57 81,57 149,33 53,3 49,38 Z M 47,14 c 26,-4 28,49 0,50 -29,-0 -28,-49 0,-50 z" />
    <path
       id="add"
       style="fill:#000000;fill-opacity:1"
       d="M 72,149 C 44,135 57,72 89,82 138,93 110,147 72,149 Z M 60,149 C 16,140 26,67 60,66 103,74 93,147 60,149 Z" />
