i know sorry!!!

OpenStudy (anonymous):

i don't get how to do it :(

OpenStudy (anonymous):

First one - use PEMDAS Method basically adding and subtracting from left to right so firl start with -5 + 6 = ? then add that with -3

OpenStudy (anonymous):

ok 1 u can do in the calculater 2reverse opperation 3same as 2 4 is simple multiplication 5 is 18 divided by 2

OpenStudy (anonymous):

oh!!

OpenStudy (anonymous):

haha thank you!

OpenStudy (anonymous):

lol np

OpenStudy (anonymous):

Second one: -21-6 just add them just remember the negative

OpenStudy (anonymous):

OpenStudy (anonymous):

ill fan everyone who helped me! since i can t medal one person

OpenStudy (anonymous):

yeah

jabez177 (jabez177):

I was going to give you the calculator option too. xD

OpenStudy (anonymous):

3rd one is simple just multiply both numbers and follow the rule if you multiply by negatives they become positive

OpenStudy (anonymous):

oh no its -18

OpenStudy (anonymous):

thx jabez

OpenStudy (anonymous):

yeah lol thts wat i meant

OpenStudy (anonymous):

4th Use PEMDAS and multiply from left to right so you would get 12 * (-4) first then multiply that answer by -5 and remember the negative and positive rule

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

the last one is just diving 18/2 and of course since they are both negative the answer becomes positive

OpenStudy (anonymous):

"dividing"

OpenStudy (anonymous):

@janaixo number 1 is just -5+6+-3 right? i just ignore the ()?

OpenStudy (anonymous):

1) -5 + 6 First = +1 then add with -3

OpenStudy (anonymous):

oh ok thank you!

OpenStudy (anonymous):

2) -21-6 = its like saying you own one friend $21 and another $6 how much do you own both together

OpenStudy (anonymous):

27$

OpenStudy (anonymous):

right but the answer would be negative so -27

OpenStudy (anonymous):

oh yeah ok thank you

OpenStudy (anonymous):

3rd one is like multiply 6*5

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

and because both are negative it becomes positive

OpenStudy (anonymous):

4th one is multiplying 12 * (-4) which -48 then multiplying -5

OpenStudy (anonymous):

last one is just diving 18 by 2 both are negative so its positive value thats it

OpenStudy (anonymous):

nun sense misan

OpenStudy (anonymous):

non?

OpenStudy (anonymous):

1+-3=-2 right?

OpenStudy (anonymous):

yes
