in simplification can bar of vinculum come over more than 2 numbers
Answers
Answer:
Examples on simplification are discussed, in order to simplify expressions involving more than one bracket by using the steps of removal of brackets. Different types of questions on simplifications are explained here step by step.
1. Simplify: 37 - [5 + {28 - (19 - 7)}]
Solution:
37 - [5 + {28 - (19 - 7)}]
= 37 - [5 + {28 - 12}] [Removing the innermost bracket ( )]
= 37 - [5 + 16] [Removing braces { }]
= 37 - 21
= 16.
Step-by-step explanation:
Simplify: 197 - [1/9{42 + (56 - 8 + 9)} +108]
Solution:
197 - [1/9 {42 + (56 - 8 + 9)} +108]
= 197 – [1/9 {42 + (56 – 17)} + 108] [Removing vinculum]
= 197 - [1/9 {42 + 39} + 108] [Removing parentheses]
= 197 - [(81/9) + 108] [Removing braces]
= 197 - [9 + 108]
= 197 - 117
= 80
