Given x 3423 y 8537 and z 2181 compute x y z and x z

Given x = 3.423. y = 8.537 and z = 2.181, compute (x + y) * z and x * z + y * z with the 4-digit decimal arithmetics with rounding.

LHS=(x+y)*z

=(3.423+5.537)*2.181

=19.5418

RHS=

x*z+y*z

x*z=3.423*2.181=7.465563

y*z=8.537*2.181 =18.619197

x*z+y*z=7.465563+18.619197

=26.08476

RHS=x*z+y*z= =26.0848 (rounded to 4 decimals)
