MATLAB: Matlab give wrong answer

Question

I have used this two equation who must give the same value but matlab give two different answer

Rs=1.150;

Rr=1.440;

Ls=0.156;

Lr=0.156;

Lm=0.143;

%*********************

A=1-(Lm^2/Lr*Ls)

B=1-((Lm^2)/(Lr*Ls))

%but 'A-b #0'

Answer 1

A and B are different. Note the order of operation

A=1-(Lm^2/Lr*Ls) is the same as A=1-((Lm^2)/Lr)*Ls
