We know that, if we add something after negative sign, the next sign must be change (if positive(+) then that will turn to negative sign, and if negative that will turn to positive. But why we applied (E - E = E - (E + E) == E -E + E ) instead of (E - E = E - (E + E) == E -E - E ) ? Thanks in advance.
