Shown on this page, Collecting Like Terms - Part 2, is a two screen snapshots of the content found in our eBook or print copy of HP Prime Guide Algebra Fundamentals.The snapshot will likely be a partial view, with previous content cut off from top and completion of a topic's explanation cut from the bottom. For additional coverage see the Table of Content of the HP Prime Guide to jump to the second Chapter, Explanation 1.2 - Operations and Properties of Real Numbers, Collecting Like Terms - Part 2, shown below. Print user will need to turn to this page.

This section continues the Additional Properties section. In Content 1 we show how the Properties of Negatives left and right expressions for individual properties are evaluated. We will use the fourth line's initial relationship that -(a+b) equals -1*(a+b)  in the Properties of Negatives screen to help us with manually eliminating grouping sysmbols.

Remark: In Content 1 calculator's screen we see how the HP Prime distributes negative sign and  -1 across parenthesis. When manually simplifying expressions, we will use the equivalent relations shown to add -1 in front of a grouping symbol. In Content 2 we can type original expressions into our calculator and it will produce the correct solution as long as we add asterisks, for multiplication, when necessary and replace all grouping symbols with parentheses.

When you finished with this section move on to another section or topic.

Instructions

Continue reading with Content 2. Follow the directions given to manually (a) Collect like terms and (b)S simplify the expressions shown. Enter part (a) directly into your calculator to get its result. For part (b) type in the command line: 2x-(3+4*(x+5y)) to get the result shown.

Note: When entering into the calculator, all grouping symbols are replaced with  parentheses. We must use an asterisk, for multiplication, between the 4 and the parentheses.
