Operating the Calculator

Now that you’re familiar with the basic layout and key features of your Casio 3502 calculator, let’s dive into how to use it for calculations. This section will guide you through performing basic arithmetic operations, exploring scientific functions, and utilizing memory features.

Basic Arithmetic Operations

Performing basic arithmetic operations like addition, subtraction, multiplication, and division is fundamental to using any calculator. The Casio 3502 makes these operations straightforward.

  • Addition: Enter the first number, press the “+” key, enter the second number, and press the “=” key. For example, to add 5 and 3, you would press “5 + 3 =” and the calculator would display “8”.
  • Subtraction: Enter the first number, press the “-” key, enter the second number, and press the “=” key. For example, to subtract 3 from 5, you would press “5 – 3 =” and the calculator would display “2”.
  • Multiplication: Enter the first number, press the “x” key, enter the second number, and press the “=” key. For example, to multiply 5 by 3, you would press “5 x 3 =” and the calculator would display “15”.
  • Division: Enter the first number, press the “÷” key, enter the second number, and press the “=” key. For example, to divide 5 by 3, you would press “5 ÷ 3 =” and the calculator would display “1.666666667”.
