$\large\textsf\red{QUESTION:}$

-987654321+(-123456789) =??

$\large\textsf\green{ANSWER:}$

$\textsf\green{- 1111111110}$

$\textsf\blue{\underline{SOLUTION:}}$

$\textsf\red{\underline{NOTE:}}$ When there is a + in front of an expression in parentheses, the expression remains the same

$\green\implies\textsf\green{- 1111111110}$

Answer 2

Answer:

$\bf\underline{\underline{Question}}$

-987654321+(-123456789)

$\bf\underline{\underline{solution}}$

from the rule of bodmas we should open the all brackets first

so, in front of -124456789 it's "+" sign

we know that [ - ] [ + ] = [ - ]

so , -123456789

→ now , it's only -987654321 -123456789

we know that [ -] [ - ] = [ + ]

àdd them up !!

= −1111111110

note : we put "-" sign if front because the largest no ( -987654321) has a minus sign too .✔
