tell me all about order of operations in math
Order of operations is a set of rules for solving mathematical equations. It is also known as the "BODMAS" rule or the "PEMDAS" rule. The letters stand for:
B - Brackets
O - Orders (exponents, roots, etc.)
D - Division
M - Multiplication
A - Addition
S - Subtraction
When working with an equation, the order of operations dictates that you must first complete any operations inside of brackets, then take care of any orders (exponents, roots, etc.), followed by division, multiplication, addition, and finally subtraction. It is important to remember the order of operations when solving equations, as it can have a major impact on the final answer.
