Grouping symbols are mathematical symbols used to indicate which operations should be performed first in an expression. The most common grouping symbols are parentheses (), brackets [], and braces {}. By using these symbols, you can clarify the order of operations and ensure that calculations are done correctly. When you see an expression with grouping symbols, start by solving the operations inside the symbols before moving on to the rest of the expression. This helps avoid confusion and errors, especially in complex calculations. Understanding how to use grouping symbols is essential for accurate problem-solving in mathematics.
