Question

s Add :(-1) +(-2) +(-8)​

Answer 1

Answer:

-11

Step-by-step explanation:

here, -1 + (-2) + (-8)

So, it will be like -1 - 2 - 8

and if digits have negative sign, then we add those digits keeping negative sign.

Hence, - (1+2+8) = -11

Answer 2

The given question is we have to add the numbers.

the numbers here are -1, -2 and -8.

The numbers are having negative sign.

on adding the numbers having the sign there are certain rules to identify the signature of the digit.

if we add the numbers having the same sign add then and put the sign as it is

for eg (+) +( +) =(+)

( -) + (-)= (-)

If we add the numbers having different sign, we have the certain rules (+) +(-) =subtract the two values mention the sign of biggest number.

(-) +(+) =same rule as above

let us see some examples for th

$2 + 2 = 4 \\ ( - 2) + ( - 2) = ( - 4) \\ ( - 2) + (4) = 2 \\ ( - 4) + (2) = - 2$

According to the rule let's add the given number we get

$( - 1) + ( - 2) + ( - 8) \\ ( - 3) + ( - 8) \\ ( - 11)$

Therefore, the final answer for the given question is -11.
