A) −10 − 13 − 17 − (−40)=

B) 111 − (31 + 78) − 7 + 14 =​

A) 0

B) 9

Step-by-step explanation:

A) −10 − 13 − 17 − (−40) [B.E.D.M.A.S rule] (First bracket)

= - 10 - 13 - 17 + 40

= 40 - 10 - 13 - 17. (Then subtraction)

= 40 - 40

= 0 (Ans)

B) 111 − (31 + 78) − 7 + 14 [B.E.D.M.A.S rule] (First bracket)

= 111 − 109 − 7 + 14. (Then addition)

= 111 + 14 - 109 - 7

= 125 - 116. (At last subtraction)

= 9 (Ans)

6.5
