Question

find-19+(-11)+(-7)+(-18)+1+(-11)​

Answer 1

Answer:

-65

Step-by-step explanation:

first you multiply the sign inside the brackets and left of the true baracket ...as follows example

1)+(-z)=-z

2)-(-z)=+z

let z be any number...

and in addition (-)+(-)=(-),(+)+(+)=(+). and if the both sign are unlike signs then we should not c9ncedure that sign and just do calculation.....after you know the answer put the largest numbers sign before the answer...

1)(+)+(-)=(+)×(-) =(-)....so we should minus them and put the largest number sign....and vise versa for subtraction.....

and let's apply this methods on the question....

let's come to question

add all numbers which are negative numbers ,-19,-11,-7,-18,-11.....= 66 and you should put negative sign before the number=(-66)

next remaining number is +1 .....

(-66)+1=(-65)..and the largest number sign is (-) ,so put minus before 65..=(-65)
