A dozen means 12, and since there are 5 dozens in the problem, you will count 12 eggs, 5 times. You need to know the total number of eggs in that basket. Multiplication makes adding the same number over and over again easier. Press "=" (the equal sign) to find the answer or the difference of the two numbers.Two is the subtrahend, the number you'll subtract from the minuend. Press "-" to tell the calculator to subtract.This number is your minuend, your starting value. Enter the number 10 into the calculator.Later, she removed 2 eggs because she found cracks in the shell. In this case, the egg lady put 10 eggs in the basket. When working with more than two addends, simply key in each number separated by the addition sign ("+") before pressing the equal sign. Press "=" (the equal sign) to find the answer or the sum of the two numbers.Press "+" to tell the calculator to add.Addends are numbers that you add together. Enter the number 5 into the calculator.In this case, you will be performing addition. Say you have a word problem asking you to find the total amount of eggs in a basket. Should this be the first time you're using a calculator, don't worry! We'll show you how. How to Solve Problems Using Our Calculator Top Field: where you will see the answer after you complete an operation.Equal Sign (=): gives you the answer to your formula.Operations: addition (+), subtraction (-), multiplication (*), division (/).Decimal point (.): for numbers with decimal places (e.g., 1.25, 2.3, etc.).AC (All Clear): clears all previous content and formulas from the system.The best way to start using our online calculator is to get to know what each button is for. Now, let's get acquainted with our free online calculator. It won't show you how to get to an answer, though, so make sure you practice your math on paper to better understand how to add, subtract, multiply, and divide! It also helps you complete simple order of operation (PEMDAS) problems. Though a calculator like this one is useful for any arithmetic operations, it really comes in handy when you start multiplying and dividing large numbers. That's where our free online calculator comes in! Perform basic math operations from the comfort of your computer. Learning to work with numbers can be challenging, but not when you have the right tools. But, if the operator doesn't matches any of the four character, the default statement is executed which displays error message.Our Online Free Calculator Allows You To Perform Simple Arithmetic Operations With Whole Numbers And Decimals. This program works similarly for the * and / operators. If user enters - then, statements for case: '-' is executed and program is terminated. If user enters + then, statements for case: '+' is executed and program is terminated. Then, switch.case statement is used for checking the operator entered by user. The operator is stored in variable op and two operands are stored in num1 and num2 respectively. This program takes an operator and two operands from the user. If the operator is other than +, -, * or /, error message is shownĬout << "Error! operator is not correct" This program takes an arithmetic operator (+, -, *, /) and two operands from a user and performs the operation on those two operands depending upon the operator entered by the user.Įxample: Simple Calculator using switch statement # include Ĭout << num1 << " + " << num2 << " = " << num1 + num2 Ĭout << num1 << " - " << num2 << " = " << num1 - num2 Ĭout << num1 << " * " << num2 << " = " << num1 * num2 Ĭout << num1 << " / " << num2 << " = " << num1 / num2
