    when adding/subtracting with signs....if the signs are the same, add them and use the same sign. If the signs are different, subtract them and use the sign of the bigger number.

    think about it....the signs are the same....so they are to be added and you would use the same sign....so it would be - 9.32....understand ?

    It can get a little confusing because adding/subtracting with signs has a whole different set of rules then multiplying/dividing with signs

    ok....after subbing your problem becomes : -3.82 - 7.5.....look familiar....signs are the same....so add and keep the same sign

    ok...after subbing your problem becomes : -1.5 - (-7.7).....little different here...we have to distribute the negative through the parenthesis changing the problem to : -1.5 + 7.7.....so the signs are different. So you subtract (7.7 - 1.5) and use the sign of the bigger number.

    because the -7.7 became + 7.7 making the sign positive

    good to hear....but like I said, these rules are different from the rules that apply to multiplying/dividing with signs. Try not to get them mixed up
