+There are 8 arithmetic instructions which have similar formats of
+instructions. They are discussed together here.
+
+The instructions are:
+ * adc: add with carry
+ * add: add
+ * and: logical and
+ * cmp: compare
+ * or: logical or
+ * sbb: subtract with borrow
+ * sub: subtract
+ * xor: logical exclusive or
+
+The format of the instructions are given below.
