Quotient of Integer ÷ Integer
[OPTN]
-
[CALC]
-
[Int÷]
The “Int÷” function can be used to determine the quotient when one integer is divided by
another integer.
Example To calculate the quotient of 107 ÷ 7

Simplification
[OPTN]

[CALC]
-
[Simp]
The “
Simp” function can be used to simplify fractions manually. The following operations can
be used to perform simplification when an unsimplified calculation result is on the display.
• {
Simp
}
U
... This function automatically simplifies the displayed calculation result using the
smallest prime number available. The prime number used and the simplified result are
shown on the display.
• {
Simp
}
n
U
... This function performs simplification according to the specified divisor
n
.
