+See `dialog_counting` app for details.
+Concepts for arithmetic operators and numbers are created. Not every number is defined, but rather decimal places and their combination, eg.
+
+{{{
+concept:(tens) [20 30 40 50 60 70 80 90]
+concept:(number_hundreds) ["{[1 "jedno"]} sto" "dvě stě" "[3 4] sta" "[5 6 7 8 "osum" 9] set" dvěsta dvěstě pěcet šescet devěcet]
+concept:(number) ["~number_hundreds {~number_tens} {~digits}" "~number_tens {~digits}" ~digits]
+}}}
+
+This way, robot can understand numbers up to 999. Concepts are used in the dialogue, passed into counting function and output result is said in the dialogue:
+
+{{{
+u:(["kolik [je jsou]" spočítej spočti] _"~number ~operator [~number ~number2]")
+    $num_expression=$1
+    ^call(ALDialogCounting.compute($num_expression))
+    c1:(_* equals nan) $1 přece nejde spočítat!
+    c1:(_* equals _*) $1 [je "by mohlo být"] {asi} {tak} $2
+
+}}}
+
+Computing function receive recognized words as parameters and have to convert the words to numbers before producing the result. `command` parameter contains recognized sentence, eg. "dvacet dva plus třináct".
+
+{{{
+m = re.match('(.*) (' + '|'.join(OPERATOR_WORDS) + ') (.*)', command)
+if m:
+  number1 = self.convert_number(m.group(1))
+  operator_word = m.group(2)
+  operator = OPERATOR_WORDS[operator_word]
+  number2 = self.convert_number(m.group(3))
+  try:
+    result = str(int(eval(str(number1) + operator + str(number2)))).replace('-','minus')
+   except:
+     result = 'nan'
+}}}
