Adding and Subtracting Integers (Whole Numbers) Calculator

How to Use the Calculator

1. Enter the Expression:

   • In the input field provided, type the expression you want to evaluate.
   • You can include any combination of integers, addition +, subtraction -, and parentheses ( and ) to group parts of the expression.

   Example 1: 5 + 3 - 7

   • This is a simple expression without parentheses.

   Example 2: 10 - (2 + 4) + 8

   • This example includes parentheses, so the calculator will handle the addition inside the parentheses first.

2. Click “Calculate”:

   • After entering your expression, click the “Calculate” button.
   • The calculator will evaluate the expression, following the standard order of operations, which prioritizes calculations inside parentheses first, followed by addition and subtraction from left to right.

3. View the Result:

   • The result of your calculation will be displayed clearly in a section below the input field.
   • Additionally, you’ll see a step-by-step breakdown of the calculation process, showing you how the calculator arrived at the final answer.

Examples

Example 1: 7 - 3 + 5

• Input: 7 - 3 + 5
• Steps:
  • First, perform 7 - 3 = 4
  • Then, add 4 + 5 = 9
• Result: 9

Example 2: 10 - (2 + 4) + 8

• Input: 10 - (2 + 4) + 8
• Steps:
  • First, calculate inside the parentheses: 2 + 4 = 6
  • Then, perform 10 - 6 = 4
  • Finally, add 4 + 8 = 12
• Result: 12

Example 3: (8 - 3) + (5 + 2) - 4

• Input: (8 - 3) + (5 + 2) - 4
• Steps:
  • Calculate inside the first parentheses: 8 - 3 = 5
  • Then, calculate inside the second parentheses: 5 + 2 = 7
  • Perform the addition: 5 + 7 = 12
  • Finally, subtract: 12 - 4 = 8
• Result: 8

Quick Tips:

• Handling Negative Numbers: If your expression includes negative numbers, ensure you correctly place the - sign directly in front of the number. For instance, 5 - (-3) will correctly handle the subtraction of a negative number.
• Order of Operations: The calculator automatically follows the order of operations, so there’s no need to manually reorder your calculations.

With these steps, you should be able to effectively use the “Adding and Subtracting Integers (Whole Numbers) Calculator” for any expressions involving addition, subtraction, and parentheses.
