"maths layout structure"
 
   just wondering whats the correct method to layout ur work
for example, if i write

LHS = x + 3
> x + 2 <=== line a
= x + 1 + 1 <=== line b

will that be right?

because for line a, i wrote the inequality sign
but i wrote " = " for line b because it refers to the line directly above, and not refering to LHS

does conventions require u to write the sign > for line b or write = to signify it refers to line a

thanks in advance

   You made it right. A symbol like "=" or ">" applies only to the two expressions between which it is located. So that, e.g.,

A = B > C > D = E

means that


  • A = B
  • B > C
  • C > D
  • D = E.

In the above, some conclusions may be made. For example, that

  • A > E,

    but this may not be the case. One may write

    A > B < C

    which would imply nothing about the relative values of A and C.
