ANAGRAM
•Is a type of word play, the result of
rearranging the letters of a word or
phrase to produce a new word or phrase,
using the original letters exactly once
•Example: CARTHORSE = ORCHESTRA

DISTRIBUTIVE

Additive Identity -states that the sum of any number and 0 is the
given number. Zero, is the additive identity.
Multiplicative Identity -states that the product of any number and
1 is the given number,
a . 1= a. One, is the multiplicative identity.

In Addition
-states that the sum of any number and its additive inverse, is zero.
The additive inverse of the number a is .a.
In Multiplication
-states that the product of any number and its multiplicative inverse or
reciprocal, is 1.The multiplicative inverse of the number a is 1.
