It was really interesting to learn the use of duplexes in squaring the algebraic expressions and it saves so much time as compared to calculating the same with the conventional method. With the conventional method , to find the square of ,suppose, say a trinomial, we write

(x+2y+5)(x+2y+5)=x(x+2y+5)+2y(x+2y+5)+5(x+2y+5) and then solve each bracket and finally add. But by using duplexes ,we can find the answer in one step.

At first, using the flag digit for division seemed somewhat difficult, but with practice it improved. Now ,with 3 figure divisor also,

it can be done easily. Also, very well understood the use of ‘proportionately’ in solving the division problems.

Thank you
