4

×2)}]=36−[18−{14−(15−2×2)}]

=36−[18−{14−(15−4)}]=36−[18−{14−11}]=36−[18−3]=36−15=21

Answer 2

Step-by-step explanation:

36−[18−{14−(15−4÷2×2)}]=36−[18−{14−(15−24×2)}]=36−[18−{14−(15−2×2)}]

                                                               =36−[18−{14−(15−4)}]=36−[18−{14−11}]=36−[18−3]=36−15=21
