Answer
Given expression:
36 - [18 - {14 - (15 - 4 ÷ 2 × 2)}] [Performing division]
= 36 - [18 - {14 - (15 - 2 × 2)}] [Performing multiplication]
= 36 - [18 - {14 - (15 - 4)}]
= 36 - [18 - {14 - 11}] [Removing parentheses]
= 36 - [18 - 3] [Removing braces]
= 36 - 15 [Removing square brackets]
= 21
36 - [18 - {14 - (15 - 4 ÷ 2 × 2)}] [Performing division]
= 36 - [18 - {14 - (15 - 2 × 2)}] [Performing multiplication]
= 36 - [18 - {14 - (15 - 4)}]
= 36 - [18 - {14 - 11}] [Removing parentheses]
= 36 - [18 - 3] [Removing braces]
= 36 - 15 [Removing square brackets]
= 21
