Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Subtraction
Subtraction is one of the essential arithmetic operations, used to find the difference between two numbers. It involves taking away the second number from the first. For example, in the expression \[8 - 14\] we subtract 14 from 8.
  • Here, 8 is called the minuend, and 14 is the subtrahend.
  • The result of this subtraction, which is \(-6\) in this case, is known as the difference.
To perform subtraction properly, pay close attention to the order of numbers. Making a mistake in the sequence can lead to incorrect results. Remember, subtracting a larger number from a smaller one will yield a negative number. In our example, 14 is greater than 8, so the difference is negative.
Negative Numbers
Negative numbers can be tricky, but they are simply numbers less than zero, found to the left on a number line. Understanding them is crucial for solving arithmetic problems involving subtraction. When you subtract a larger number from a smaller one, like in the expression \[8 - 14\], you get a negative number: \(-6\).
  • Negative numbers have a minus sign \((-)\).
  • They indicate a value less than zero.
Think of negative numbers as having a debt or a below-zero temperature. Did you notice a pattern? When the minuend is smaller than the subtrahend in subtraction, the answer is negative. The number line is a handy tool to visualize how negative numbers work, where moving left from zero results in negative values.
Graphing Calculator
A graphing calculator can be a powerful tool for checking your arithmetic calculations. It provides a visual confirmation of your results and can handle complex equations with ease. To check our subtraction \[8 - 14\], we simply input this expression into the graphing calculator:
  • Enter the expression as is: 8 - 14.
  • The calculator processes the calculation.
  • Verify that it displays the result \(-6\).
Using a calculator not only helps in confirming the correctness of your manual calculations but also builds confidence in your understanding of arithmetic operations. Make sure to use it as a tool to complement your learning, ensuring that you fully grasp the operations you're working with.
