The Constant Feature

Use your computer's calculator to complete each example.

Chain-logic calculators and your computer's calculator have an automatically feature called the constant feature which repeats the same operation over and over with reduced keystrokes by using the equal sign, [=].

Here we use the constant feature to count by some constant.

• Enter the initial number,
• Press [+] to add some constant or [-] to subtract some constant,
• Enter the constant to be added or subtracted,
• Press the [=] again and again displaying each new result
 Example #1: The Three Times Tables [0][+][3][=] is 3, [=] is 6, [=] is 9, ...

 Example #2: Counting Down from 10 [10][-][1][=] is 9 [=] again is 8 [=] again is 7 ... [=] again is 0, BLAST OFF! [=] again is -1 [=] again is -2, ...
