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 ?

- texaschic101

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

- anonymous

wait i was wrong it was A

- texaschic101

it is A....signs are the same...so you add and keep the same sign

- anonymous

got another one ?

Evaluate m – n when m = –1.5 and n = –7.7.
A.
–9.2
B.
–6.2
C.
6.2
D.
9.2

- anonymous

A?

- texaschic101

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.

- anonymous

C the bigger number is positive

- anonymous

i might have done something wrong

- texaschic101

correct :)

- texaschic101

because the -7.7 became + 7.7 making the sign positive

- anonymous

yay i got a 100 and now i under stand this =)

- texaschic101

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

- anonymous

ok :)

- anonymous

you are the best :)

- anonymous

see ya thanks

- texaschic101

lol....I don't know about that...but thank you :)
