Question

The value $\left\{ {} \right\}$ are called
A. round braces
B. box braces
C. curly braces
D. none of these

Answer 1

Hint: In this type of question where the given braces are to be determined one must know the various types of the braces. The various types of braces are square braces, parentheses, curly braces and angle braces.

Complete step-by-step solution:
One must know the different braces in order to solve the question.
They can be seen in an expression where different operations are to be done but their priorities are different. These parentheses are mainly seen in an equation which to be solved using BODMAS rule, for example in the expression $\left[ {3 \times \left( {4 - 7} \right) - \left( {7 - 9} \right)} \right]$ the operation which are inside the braces are solved first and then the final answer Is to be calculated but if the expressions are not solved in accordance with the order of braces then it might lead to the wrong answer. Parentheses are used to group different numbers together. Curly braces are used to denote the set elements.
As it can be seen that in the given question the braces shown are $\left\{ {} \right\}$ and this one is curly braces.
$\therefore $ Option (C) is correct.

Note: If the question asks for $\left[ {} \right]$ braces then it is called square braces. If the question asks for $\left( {} \right)$ braces then it is called parentheses. Do not get confused with the curly braces, parentheses and square braces as they all are different. Always try to solve the question step by step so that the wrong step can be found quickly and then changed.
