### Acre

An acre is an Imperial measurement of area, usually used to measure land.

1 acre = 4,840 square yards

### Absolute Value

*Absolute value* shows How far a number is from zero.

Example “**6**” is 6 units away from **zero**, and “**-6**” is also 6 away from zero.

So, the absolute value of 6 is 6, and the absolute value of -6 is also 6.

The symbol “*|*” is placed either side to mean “*Absolute Value*“, so we can write: **|-6| = 6**

### Abscissa

**Abscissa** is the “* x*“ value in a pair of coordinates. It’s always written first in an ordered pair of coordinates such as (12,5).In the example above, the value “12” is the abscissa. (The second value “

**5**“ is called the Ordinate)
