Question

A=1995 x 1994 - 1/1993 x 1995 + 1994

 

Answer 1

\(A=\dfrac{1995\times1994-1}{1993\times1995+1994}\)

\(A=\dfrac{1995\times\left(1993+1\right)-1}{1993\times1995+1994}\)

\(A=\dfrac{1995\times1993+1995-1}{1995\times1993+1994}\)

\(A=\dfrac{1995\times1993+1994}{1995\times1993+1994}\)

\(A=1\)
