Operation types
Four operations: addition, subtraction, multiplication, and division Operation using the [+], [], [×],
[
÷], and [=] keys
Power, reciprocal operations
a [
×] [=] ..........pressing [=] for n 1 times gives a to the power of n.
a [
÷] [=] ..........pressing [=] for n + 1 times gives a to the power of n.
Percentage operations
a [
×] b [%] calculates ab/100.
a [
×] [%] calculates a2/100.
a [
÷] b [%] calculates 100a/b.
Add-on operations
a [
+] b [%] calculates a + ab/100.
Then, c [%] calculates a
+ ac/100.
Or, a [
×] b [%] calculates ab/100, then [+] [=] calculates a + ab/100.
Percent discount operations
a [
] b [%] calculates a ab/100.
Then, c [%] calculates a
ac/100.
Or, a [
×] b [%] calculates ab/100, then [] [=] calculates a ab/100.
Mark-up operations
a [
×] b [MU] calculates a/(1 b/100).
Then, [MU] calculates a/(1
b/100) a.
Mark-down operations
a [
÷] b [MU] calculates a/(1 + b/100).
Then, [MU] calculates a/(1
+ b/100) a.
Change rate operations
a [
+] b [MU] calculates 100 (a + b)/b
a [
] b [MU] calculates 100 (a b)/b
TAX operations
Tax rate: b%
a [
+TAX] calculates ab/100 + a.
a [
TAX] calculates a/(1 + b/100)
Constant operations
When a calculation ends after the [=] and [%] keys are pressed, constant mode is automatically
entered.
In multiplication, the operand is retained as a constant; in addition, subtraction, and division, the
operator is retained as the constant.
The results of addition, subtraction, multiplication, and division are all retained. There is no need
to enter numerals again. Pressing the [
=] and [%] keys calculates the retained constant using the
displayed value.
Note that the [%] key does not function in constant mode for addition and subtraction.
Percent discount and add-on operations using the [%] key do not enter constant mode.
Constant mode is canceled by clearing the operation status or pressing the [+], [], [×], or [÷] key
again.
