What are the four fundamental math concepts used in evaluating an expression?
Evaluating math expressions is difficult, if not impossible, if you do not know the four basic math concepts used. Understanding these elementary math concepts will ensure that you are able to evaluate even the most difficult expressions.IdentificationThe four basic math concepts used to evaluate an expression are multiplication, division, addition and subtraction.MisconceptionsA common misconception by someone who is not familiar with evaluating math expressions is that you perform the calculations from left to right. This is not the case.Order of OperationsThe general rule of thumb is that moving from left to right, multiply first, then divide, then add, then subtract.ExceptionsThe exception to the order of operations exists when there are a set of parentheses around a set of numbers. Calculate the expression inside each set of parentheses before completing the rest of the expression.WarningTake your time when evaluating an expression. Going too fast and rushing through a math proble
