• Page 2 Algebraic mode is the way many newer HP calculators work. It is also the way most other calculators work. To add 1 and 2, keys are pressed in the order 1Ù2Ï as shown in Figure 1. This way of working is most suitable when the user just needs to type a formula and get an answer.
• Page 3 In this example, the two numbers have been calculated already (assuming you have just completed the previous example). One is shown on the lower line, so it is enough to press Ù begin the addition. The HP 35s will the show the display in Figure 3.
• Page 4 “interactively” rather than merely keying in a problem that is already written out. However you need to solve your problem, the HP 35s can handle it. Another example - the area of a piece of carpet Here is another example to show how arithmetical calculations involving addition and multiplication are carried out using parentheses in algebraic mode.
• Page 5 In algebraic mode, digits in a number that is being typed can be deleted with the ~ key. If a number has been completed or calculated, this key deletes it completely. hp calculators - 5 - HP 35s Using Algebraic Mode - Version 1.0...
• Page 6 – where the next key pressed will be entered. This insertion point is exactly where it should be to enter the first argument. Now type 69. This is the first argument. To move past the comma, press Õ. Now press 2Ï. hp calculators - 6 - HP 35s Using Algebraic Mode - Version 1.0...
• Page 7 Algebraic operator precedence In algebraic mode the HP 35s calculates using “operator precedence”. This means that a combination of several Ù and Ã operations (or several ¸ and ¯ operations) is calculated from left to right, but ¸ and ¯ have a higher “precedence”...
• Page 8 This example shows how to edit an expression in algebraic mode. While somewhat trivial, it would certainly be easier to edit a much larger expression to correct a mistake than retyping the entire expression all over again. hp calculators - 8 - HP 35s Using Algebraic Mode - Version 1.0...
