This week I learned about absolute value of a real number. Every real number can be represented as a point on a number line. The sign of the number indicates its position relative to 0. The magnitude of the number indicates its distance from 0.

The absolute value of -6 is  |-6|=6

Example:

|6-4| (7+9) – 6 (4-6)

= |2| (16) – 6 (-2)

= 2(16) – (-12)

= 32 +12

= 44
