hey all..
can anybody help me with an 8086 assembly source code for a simple calculator??
it has the following specifications :

• The calculator should perform a signed addition (+), subtraction (-), Multiplication (*),
and division.
• The calculator takes two operands only.
• The user can use the (-) unary operator to determine if the number is negative
otherwise it is positive.
• Division should be developed so that the result should appear in floating point
representation.
• The operands have a maximum size of 3-digits 0-999).
• All operands are entered in decimal form.
• The operation should appear as in the following :

WELCOME TO MY CALCULATOR!!
