5. Numerical Calculations
The following explains the numerical calculation operations included in the function menu
displayed when K4(CALC) is pressed. The following calculations can be performed.
• {Int÷}/{Rmdr}/{Simp} ... {quotient}/{remainder}/{simplification}
• {Solve}/{d/d
x}/{d

k 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
AbahK4(CALC)6(g)
6(g)1(Int÷)h
w
k Remainder of Integer ÷ Integer [OPTN]-[CALC]-[Rmdr]
The “Rmdr” function can be used to determine the remainder when one integer is divided by
another integer.
Example To calculate the remainder of 107 ÷ 7
AbahK4(CALC)6(g)
6(g)2(Rmdr)h
w
