How to Find Remainder in Calculator: A Step-by-Step Guide
Calculators are a staple in many fields of study, including math, science, engineering, and finance. They are used to simplify complex calculations and save time. One common calculation that is often performed on calculators is finding the remainder of a division operation.
Finding the remainder of a division operation is a basic mathematical operation that is used to determine the leftover amount after dividing one number by another. It is often used to solve real-world problems such as dividing a group of objects into equal groups or determining the number of leftover items after dividing a certain number of items among a group of people.
While it is possible to manually calculate the remainder of a division operation, using a calculator can save time and reduce the likelihood of errors. There are various methods and tools available to find the remainder of a division operation on a calculator, and understanding how to use them can be helpful in many fields of study.
Understanding Remainders
Definition of Remainder
A remainder is the amount left over after dividing one number by another. For example, if you divide 10 by 3, you get a quotient of 3 with a remainder of 1. The remainder is the amount that does not fit evenly into the divisor. In this case, the divisor is 3 and the remainder is 1.
Division and Remainders
When you divide one number by another, you can either get a whole number quotient or a quotient with a remainder. If the quotient is a whole number, then the division is said to be exact. If the quotient has a remainder, then the division is said to be inexact.
To find the remainder in a division problem, you can use a calculator or do the division by hand. If you are using a calculator, you can enter the division problem and the calculator will give you the quotient and the remainder. If you are doing the division by hand, you can use long division to find the remainder.
In long division, you divide the dividend by the divisor and write the quotient above the dividend. Then you multiply the divisor by the quotient and write the product below the dividend. You subtract the product from the dividend and write the remainder below the subtraction line. If the remainder is zero, then the division is exact and you have found the quotient. If the remainder is not zero, then you continue the division by bringing down the next digit of the dividend and repeating the process.
Understanding remainders is important in many areas of math, including algebra, geometry, and calculus. It is also useful in everyday life, such as when dividing up a pizza or splitting a bill with friends. By understanding how to find remainders, you can solve a variety of problems and make more informed decisions.

Remainder Calculation Function
A scientific calculator has a Remainder Calculation function that can be used to find the remainder of a division operation. This function is also referred to as the Modulus function. It is represented by the symbol "%" on most calculators.
To use this function, the user needs to enter the dividend, followed by the modulus symbol "%" and then the divisor. For example, to find the remainder of 25 divided by 7, the user would enter "25 % 7" into the calculator. The calculator will then display the remainder, which in this case is 4.
Step-by-Step Procedure
To find the remainder of a division operation using a scientific calculator, the following step-by-step procedure can be used:
- Enter the dividend into the calculator
- Press the modulus symbol "%"
- Enter the divisor
- Press the equals sign "=" to display the remainder
For example, to find the remainder of 346 divided by 7, the user would follow these steps:
- Enter "346" into the calculator
- Press the modulus symbol "%"
- Enter "7"
- Press the equals sign "=" to display the remainder, which is 5
It is important to note that the Remainder Calculation function only works with integer values. If either the dividend or divisor is a decimal number, the calculator will display an error message. In such cases, the user will need to convert the decimal number to an integer before using the Remainder Calculation function.
Using a Graphing Calculator
Graphing calculators are powerful tools for performing advanced mathematical operations, including finding remainders. Here are some tips for using a graphing calculator to find remainders.
Accessing Advanced Functions
Most graphing calculators have a variety of advanced functions that can be used to find remainders. One such function is the modulus operator (%), which returns the remainder of a division operation. For example, to find the remainder of 23 divided by 5, simply enter "23 % 5" into the calculator and press enter. The result will be 3, which is the remainder of the division.
Another useful function is the integer division operator (//), which returns the quotient of a division operation. To find the quotient and remainder of a division operation, use both the modulus and integer division operators. For example, to find the quotient and remainder of 23 divided by 5, enter "23 // 5" to find the quotient (4) and "23 % 5" to find the remainder (3).
Programming the Remainder Operation
Some graphing calculators also allow users to program custom operations, including the remainder operation. To program the remainder operation, users can create a new function that accepts two arguments (the dividend and divisor) and returns the remainder of the division operation.
For example, on a TI-84 Plus graphing calculator, users can create a new function by pressing the "PRGM" button, selecting "NEW", and entering a name for the function (e.g. "remainder"). Then, users can enter the following code to define the function:
:Func:remainder(Dividend,Divisor)
:Return:Dividend-Divisor(int(Dividend/Divisor))
:EndFunc
Once the function has been defined, users can call it by entering "remainder(Dividend,Divisor)" into the calculator, where "Dividend" and "Divisor" are replaced with the appropriate values. For example, to find the remainder of 23 divided by 5 using the custom "remainder" function, enter "remainder(23,5)" into the calculator and press enter. The result will be 3, which is the remainder of the division.
By using these advanced functions and programming custom operations, users can easily find remainders on their graphing calculators.
