+#X text 29 171 The example below performs basic addition with two numbers:
+i.e. a + b = c;
+#X text 28 54 All of these objects operate the same way. The right
+inlet sets or changes the numeric value of the object. Sending a number
+to the left inlet forces the object to perform the operation with the
+current numeric value of the object and output the result. A "bang"
+will output the result without changing the numeric values at either
+inlet. A creation argument can be used to define the initial numeric
+value of the right inlet.;
