Short Answer

Expert verified

The value of $18-35$ is $-17$.

Step by step solution

Identify the operation

The expression given is $18-35$. The operation involved here is subtraction.

Compute the Subtraction

To compute $18-35$, perform the subtraction operation, which involves finding the difference between 18 and 35.

Understand Subtraction with Negative Result

Since 35 is larger than 18, the result will be a negative number. Specifically, $18 - 35 = -17$.

Key Concepts

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

Subtraction

Subtraction is one of the fundamental operations in arithmetic. It involves taking one number away from another. In the exercise given, we are asked to compute $ 18 - 35 $. When subtracting, we start with the 'minuend' (the first number) and subtract the 'subtrahend' (the second number).

Minuend: 18
Subtrahend: 35

To perform the subtraction, we find the difference between these two numbers. Since 35 is larger than 18, we end up with a negative result.

Negative Numbers

Negative numbers are numbers less than zero, represented with a minus sign (-). When we subtract a larger number from a smaller one, the result is a negative number. In our example, exposing students to this concept is crucial. The computation $ 18 - 35 $ results in $ -17 $ because 35 is greater than 18.
Understanding negative numbers is vital in mathematics since they help describe values less than zero, such as debt or temperature below freezing. Here's how to handle them:

Know that the minus sign means 'below zero.'
Negative results occur when subtracting a bigger number from a smaller one.

Getting comfortable with negative numbers allows us to solve various real-world problems.

Basic Arithmetic

Basic arithmetic covers fundamental operations such as addition, subtraction, multiplication, and division. In our example, we focused on subtraction, one of these core concepts. Mastering these operations is essential for advancing in math.
Here's a recap of how it works in subtraction:

Identify the numbers involved.
Determine which number is larger.
Subtract the smaller number from the larger and adjust sign accordingly.

For $ 18-35 $, we determined that 35 is larger than 18, so the result is negative. Practicing these basic skills builds a strong foundation for more complex mathematics challenges ahead.
