Parentheses Braces Square Bracket

Square Brackets are the Last one to be solved; when there are more than one type of brackets. Square brackets are denoted with the symbol "[ ]".

Following are some examples which shows the working of Square Brackets, Curly Braces & Parentheses

Example 1 = Solve 80 + [10{10 - (3 + 2)}]
Answer = Here we have three types of brackets, so we solve the Parentheses first and we get:
= 80 + [10{10-(5)}]
= 80 + [10{10-5}]
Now, solve the Curly Braces and we get:
= 80 + [10 × 5]
Now, solve the Square Brackets and we get:
= 80 + 50 = 130

Example 2 = Solve 2 [10 + {5 - (2 × 3)}]
Answer = Here we have three types of brackets, so we solve the Parentheses first and we get:
= 2 [10 + {5 - (6)}] = 2 [10 + {5 - 6}]
Now, solve the Curly Braces and we get:
= 2 [10 + {-1}]
= 2 [10 - 1]
Now, solve the Square Brackets and we get:
= 2 × 9 = 18

Example 3 = Solve 100 - [20 + {5(40 ÷ 4) - (2 × 2)}]
Answer = Here we have three types of brackets, so we solve the Parentheses first and we get:
= 100 - [20 + {5 × 10 - 4}]
Apply the BODMAS Rule and solve Curly Braces and we get:
= 100 - [20 + 46]
Now, solve the Square Brackets and we get:
= 100 - 66 = 34
