Getting startedYou may want to practice getting a feel for your calculator keysby reading through the key definitions and learning how to enterbasic feet-inch-fractions and metric, how to store values inMemory, etc., before proceeding to the examples.Order of OperationsUnlike other Calculated Industries calculators, which use theChaining Method of Operations, this calculator uses the Orderof Operation Method. Chaining Method (“as entered”): 10 4 x 5 70 Order of Operations: 10 4 x 5 30The Order of Operations method of computing is based on thefollowing order of precedence:1) Expressions inside of parentheses2) Single-variable functions that perform the calculationand display the result immediately (trig functions, square,square root, xy, percent, reciprocal, angle conversions)3) Multiplication and division4) Addition and subtraction5) Equals (completes all operations)If you need to calculate using the Chaining Method, you canchange this in your calculator Preference Settings.User’s Guide — 7
Using ParenthesesYour calculator has parentheses keys and for performingmathematical operations. (In the Order of Operations method,expressions inside of parentheses are performed first.)The calculator offers up to 21 levels of parenthesis:1) First parenthesis level opened – press for one rightsided parenthesis.2) Second level opened – press a second time for tworight-sided parentheses .3) Third level opened – press a third time for three rightsided parentheses .4) Fourth level opened – press a fourth time for four rightsided parentheses .Numbers of levels greater than four are shown in the upperleft corner of the display.8 — Pipe Trades Pro
