Answer 2

Solution :-

→ 199 + (-20) + (-11)

→ 199 + [-20 + (-11)]

taking (-1) common from bracket now,

→ 199 + (-1)[20 + 11]

→ 199 + (-1) * 31

→ 199 + (-31)

→ 199 - 31

→ 168 (Ans.)

Method 2) :-

→ 199 + (-20) + (-11)

• (+) and (-1) change into (-1) .

so,

→ 199 - 20 - 11

→ 199 - 31

→ 168 (Ans.)
