When doing computations,always follow the order of operations and always perform the operations according to the following rules. Rule #1: 1. If grouping symbols are used such as parentheses, perform the operations inside the grouping symbols first. 2. Evaluate any expressions with exponent 3. Multiply and Divide from left to right.

The FOIL method is a special case of a more general method for multiplying algebraic expressions using the distributive law. The word FOIL was originally intended solely as a mnemonic for high-school students learning algebra. The term appears in William Betz s 1929 text, Algebra for Today, where he states. The mathematical order of operations is very important on the PSAT/NMSQT math sections. Please Excuse My Dear Aunt Sally (PEMDAS) is a mnemonic (memory aid) that helps you remember which operation comes first, which comes second, and so forth. The order matters because if you ignore Aunt Sally, you end up with the wrong answer. In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression. For example, in mathematics and most computer languages, multiplication is granted a higher precedence than addition, and it has been this way since.
M ultiplication and D ivision, in order from left to right; A ddition and S ubtraction, in order from left to right. Using the first letters of these operations, we get PEMDAS, from which we get the most famous of all mathematical mnemonics. Memory Tricks: Mnemonics for Order of Operations.

BEDMAS is an acronym to help remember an order of operations in algebra basics. When you have math problems that require the use of different operations ( multiplication , division, exponents, brackets, subtraction, addition) order is necessary and mathematicians have agreed on the BEDMAS/PEMDAS order. Each mnemonic is intended to convey “parentheses, exponents, emphasis on exponents and teaching the order of operations as a key part of equations, functions, and statistics, while reinforcing critical mathematical practices. Explains the order of operations ( PEMDAS or BODMAS ) in plain terms, points more properly, the acronym ) PEMDAS , which is turned into the mnemonic.
