# Parentheses and Dashes

## By EnglishI PLC

This instructional video presents how to use parentheses and dashes in writing. The instructor tells students that using these two kinds of punctuation are on opposite ends on the emphasis spectrum. Parentheses are used to play down information and dashes are used to add emphasis.

This Screencast was completed using Dabbleboard and shows how changing removing or eliminating parentheses with similar numbers can change the outcome. The instructor reviews the order of operations as she works the same problem in two different ways based on placement of parentheses.

# Evaluating Expressions with Parentheses and Braces and Brackets

## By HoodaMathTutorials

The instructor dressed as a pig shows how to solve expressions using parentheses braces and brackets. He explains that when these symbols are used they mean to "do me first" in order of operations.

# Grouping Symbols - Parentheses Brackets and Braces

## By yourteachermathhelp

The instructor shows how to solve an expression with three different grouping symbols. She begins by simplifying within the innermost grouping symbol the parentheses. She then moves out to the brackets. Lastly she moves out to the braces. She rewrites the problem after each step when simplifying within each grouping symbol.

In this example, we’re asked to factor 125p cubed + 1. Notice that 125p cubed is a perfect cube, because 125 is 5 times 5 times 5, or 5 cubed, and 1 is a perfect cube, because 1 is 1 times 1 times 1, or 1 cubed. So we have the sum of two cubes. To factor the sum of two cubes, we use the following formula: a cubed + b cubed can be factored as parentheses a + b times parentheses a squared – ab + b squared. And in this problem, since a cubed is represented by 125p cubed, the value of a is 5p, and since b cubed is represented by 1, the value of b is 1. Notice that the value of a, 5p, has both a coefficient and a variable, so we need to use parentheses around the 5p when we plug it into the formula, in order to keep the 5 and the p together. And let’s go ahead and use parentheses around our x as well, in order to be consistent. So we have bracket parentheses 5p + parentheses 1 closed bracket times bracket parentheses 5p squared + parentheses 5p times parentheses 1 + parentheses 1 squared closed bracket. Notice that we change the parentheses in the formula to brackets so that we’re not dealing with too many sets of parentheses. Next, simplifying inside of the second set of brackets, parentheses 5p squared is 5p times 5p, or 25p squared, 5p times 1 is 5p, so we have – 5p, and parentheses 1 squared is 1, so we have plus 1. And changing the brackets back to parentheses, we have parentheses 5p + 1 times parentheses 25p squared – 5p + 1, which is our final answer.
