The rules for removing parentheses. Parentheses will be preceded either by a plus sign + a + (b −c + d) or a minus sign −. a − (b −c + d). When parentheses are preceded by a plus sign + simply remove them. Nothing changes. a + (b −c + d) = a + b − c + d. When parentheses are preceded by a minus sign − change the sign of every term within the parentheses.

There are four rules for using parentheses as punctuation marks in written American English: Enclose numbers and letters in a list Enclose clarifications Enclose emphasizations Enclose asides and additional information The following sections explain and provide examples Rules or Laws of Logarithms In this lesson, you’ll be presented with the common rules of logarithms, also known as the “log rules”. These seven (7) log rules are useful in expanding logarithms, condensing logarithms, and solving logarithmic equations. In addition, since the inverse of a logarithmic function is an exponential function, I would also … Logarithm Rules Read More » The letters a and b mean: the numbers that are in the numerators. The letter c means: the number in the denominator. The rule means: "Whatever those numbers are, add the numerators and write their sum over the common denominator." Algebra is telling us how to do any problem that looks like that. That is one reason why we use letters.

PEMDAS Rule. The PEMDAS Rule (an acronym for “Please Excuse My Dear Aunt Sally”) is a set of rules that prioritize the order of calculations, that is, which operation to perform first. Otherwise, it is possible to get multiple or different answers. We don’t want that to happen. Below illustrates an example where there are two possible answers.
