HP HP-20S - Arithmetic Operators

Arithmetic Operators. The following examples demonstrate using
the arithmetic operators [(+], (-], (x], (+], and (exponentiation)*.
Keys: Display: Description:
24.715 62.471 (=] 87.1860 Adds 24.715 and
62.471.
When a calculation has been completed (by pressing (=]), pressing a
number key starts a new calculation:
19 12.68 (=] 240.9200 Calculates 19 x 12.68.
is the exponentiation operator:
4.7 3(=) 103.8230 Calculates 4.75.
If you press an operator key after completing a calculation, the cal-
culation is continued:
115.5 115.5_ Continues the
calculation.
(=) 219.3230 Completes the calcula-
tion of 4.73 + 115.5.
You can do chain calculations without using (=] after each step. Calcu-
late 6.9 X 5.35 + 0.918:
6.9 5.35 [+] 36.9150 Pressing [+] displays
the intermediate an-
swer, showing result of
6.9 X 5.35.
918 0.918_ Continues the
calculation.
(=) 40.2124 Completes the
calculation.
*If you press more than one operator, for example (+][=] (+], all are ignored except
the last one.
