(A+b)+c=a+(b+c)

Solution for (A+b)+c=a+(b+c) equation:

Simplifying
(A + b) + c = a + (b + c)

Remove parenthesis around (A + b)
A + b + c = a + (b + c)

Remove parenthesis around (b + c)
A + b + c = a + b + c

Add '-1b' to each side of the equation.
A + b + -1b + c = a + b + -1b + c

Combine like terms: b + -1b = 0
A + 0 + c = a + b + -1b + c
A + c = a + b + -1b + c

Combine like terms: b + -1b = 0
A + c = a + 0 + c
A + c = a + c

Add '-1c' to each side of the equation.
A + c + -1c = a + c + -1c

Combine like terms: c + -1c = 0
A + 0 = a + c + -1c
A = a + c + -1c

Combine like terms: c + -1c = 0
A = a + 0
A = a

Solving
A = a
