When it comes to evaluating expressions involving absolute value, it’s essential to understand how it works and what its properties are. In mathematics, the absolute value of a number is its distance from zero on a number line, regardless of its sign. For example, the absolute value of 5 is 5, and the absolute value of -5 is also 5. Now, let’s explore what 1 – 1 equals in absolute value.
Understanding absolute value
To calculate the absolute value of a number, you simply ignore its sign. This means that positive numbers remain the same, and negative numbers become positive. The absolute value function can be denoted by vertical bars surrounding the number or expression. For instance, |x| represents the absolute value of x.
What is 1 – 1 in absolute value?
To determine what 1 – 1 equals in absolute value, we first need to calculate the difference between the two numbers, which results in 0. Next, we apply the absolute value function and obtain the absolute value of 0. Since 0 is neither positive nor negative, its absolute value is also 0.
**Therefore, 1 – 1 in absolute value is equal to 0.**
