Finding all numbers with a given absolute value

The absolute value is defined as

|a| = +a, if a is positive

|a| = −a, if a is negative

|0| = 0

So, the absolute of any number (other than 0) is always positive.

Formula

All the numbers with a given absolute value ‘a’ are therefore, a and −a.

Find the absolute value of the following number:

48

Solution

Step 1:

|+48| = 48; |−48| = 48

Step 2:

So, the numbers with given absolute value 48 are +48 and −48.

Find the absolute value of the following number:

33

Solution

Step 1:

|+33| = 33; |−33| = 33

Step 2:

So, the numbers with given absolute value 33 are +33 and −33.

Find the absolute value of the following number:

97

Solution

Step 1:

|+97| = 97; |−97| = 97

Step 2:

So, the numbers with given absolute value 97 are +97 and −97.
