- Addition and Subtraction (from left to right)

Understanding and adhering to the order of operations ensures that mathematical expressions are solved consistently and correctly.

By following this sequence, mathematicians and students can avoid ambiguity and arrive at the accurate solutions for complex expressions.

### Symbol Meanings in Math

Symbol meanings in math are essential for understanding the functions and operations represented by commonly used arithmetic symbols.

The plus symbol (+) indicates addition, the minus symbol (-) signifies subtraction, the multiplication symbol (×) represents multiplication, and the division symbol (÷) denotes division.

Parentheses () are used to indicate the order of operations or to group numbers and operations together. The equals sign (=) is used to show that two quantities are the same.

Additionally, the percent symbol (%) denotes a proportion out of 100, and the greater than (>) and less than (<) symbols are used to compare the magnitude of two numbers.

Understanding these meanings is crucial for correctly interpreting and solving mathematical equations.
