Question

What does it mean when you have a bracket or two straight lines around a negitive number

Answer 1

When you see a bracket or two straight lines around a negative number, it indicates absolute value. Absolute value refers to the magnitude or distance of a number from zero on a number line, without considering its sign.

Step-by-step explanation:

When you see a bracket or two straight lines around a negative number, it indicates absolute value. Absolute value refers to the magnitude or distance of a number from zero on a number line, without considering its sign. It is denoted by enclosing the number within brackets or two straight lines. When a number is absolute, it is always positive or zero.

For example, the absolute value of -5 is written as | -5 |, which evaluates to 5. This shows that the distance between -5 and 0 on the number line is 5 units.

In some cases, the absolute value function can also be represented using a single straight line, such as |x|. This indicates that regardless of the sign of x, the output will always be positive or zero.

Answer 2

When you have a bracket around any number, you need to turn that number into the greatest integer less than or equal to that number. Which means if don't have an integer, round it down to nearest integer.

Ex. [3]=3 [4.87]=4 [8.24]=8

The two straight lines make its inside positive.

Ex. |3.14|=3.14 |-4|=4 |-7/3|=7/3
