The use of grouping symbols in math shows us which part of the problem or expression should be done first. Brackets, braces and parentheses are common grouping symbols used in mathematics. If no symbol is shown between brackets, forexample, (3+7)(8+1) it means that you should multiply after simplifying the operations inside the brackets.
Answer: Grouping symbols in mathematics are the symbols which are used to group numbers or variables.There are three common types of grouping symbols such as parentheses ( ), brackets [ ], and braces { }.
There are some rules such as PEDMAS [parentheses,exponents,divide,multiply,addition,subtraction]or BEDMAS [brackets,exponents,divide,multiply,addition,subtraction] and BODMAS [bracket,of,divide,multiply,addition,subtraction] which are used in sequence from left to right to organize information appropriately and simplify the problem to get the answer.
