In some regions it is also known as PEDMAS - Parentheses Exponents Division Multiplication Addition and Subtraction. This rule explains the order of operations order of precedence to solve an expression. In this case thats 5 2 25.
O of Order D Division.
According to BODMAS rule if an expression contains brackets we have first to solve or simplify the bracket followed by order that means powers and roots etc then division multiplication addition and subtraction from left to right. Some people prefer to call it PEMDAS P - Parentheses E - Exponents M - Multiplication D - Division A - Addition and S - Subtraction while others use GEMDAS G - Grouping. That order of operations takes the form of BODMAS rule in mathematics. Next division and multiplication.
