Conditions and Rules
A few conditions and rules for general simplification are given below:
Condition Rule
x + (y + z) ⇒ x + y + z Open the bracket and add the terms.
x – (y + z) ⇒ x – y – z Open the bracket and multiply the negative sign with each term inside the bracket.
(All positive terms will be negative and vice-versa)
x(y + z) ⇒ xy + xz Multiply the outside term with each term inside the bracket
BODMAS RULE
BODMAS is an acronym and it stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction. In certain regions, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction) is used, which is the synonym of BODMAS.
It explains the order of operations to be performed while solving an expression. 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. Solving the problem in the wrong order will result in a wrong answer.
Note: The “O” in the BODMAS full form is also called “Order”, which refers to the numbers which involve powers, square roots, etc. Check the examples below to have a better understanding of using the BODMAS rule.
