Once you get used to that way, it is nolonger necessary to actually write it that way. It is helpful to always thinkof minus signs as being “stuck” to the term directly to their right. That way,as you rearrange terms, collect like terms, and clear parentheses, the “addingthe opposite” business will be taken care of because the minus signs will gowith whatever was to their right.
