-35/12
OpenStudy (calculusxy):
I meant 5/3 to be a fraction that is completely negative.
OpenStudy (calculusxy):
Can someone please help me? I am not too good with negatives.

-a*b = -(a*b)
ganeshie8 (ganeshie8):
-5/3 x 7/4 = -(5/3 x 7/4)
OpenStudy (calculusxy):
So it will be 35/12 completely negative right?
ganeshie8 (ganeshie8):
-35/12

(-35)/12 = 35/(-12) = -(35/12)
OpenStudy (calculusxy):
So can you please help with the negatives with addition, subtraction, multiplication, and division.
OpenStudy (calculusxy):
Like can you explain to me them? E.g. 14-(-11) =25?

Can you explain to me the steps?
OpenStudy (calculusxy):
Seven
ganeshie8 (ganeshie8):
add them up,
then divide by 7
ganeshie8 (ganeshie8):
average value = (20 + 6 + -5 + -8 + 4 + 14 + -3) / 7
OpenStudy (anonymous):
When in doubt, listen to ganeshie.

So let's say it's 26+(-5)= 21
21+ (-8) = 13
13 + 4 = 17
17 + (-18)=-1
-18 + -3 = -21?
So I made couple of mistakes in the numbers.
OpenStudy (calculusxy):
Basically if you add two negative numbers will
THey also equal negative
ganeshie8 (ganeshie8):
So let's say it's 26+(-5)= 21
21+ (-8) = 13
13 + 4 = 17
`17 + (-18)=-1`
-18 + -3 = -21?
ganeshie8 (ganeshie8):
why are you adding -18 in that line ?
OpenStudy (calculusxy):
I made a mistake in the list of the numbers.

Anyway, will -18 + -3 equal to -21?
OpenStudy (calculusxy):
I got the answer, thanks for ur help :)
ganeshie8 (ganeshie8):
if you borrow $18 from me today
and again borrow $3 from me
how much do you owe me ?
ganeshie8 (ganeshie8):
-18 + -3 = -21
