Translation
In Euclidean geometry, a translation is a geometric transformation that moves every point of a figure or a space by the same distance in a given direction.
Exponents
Exponents can be though of as repeated multiplication, meaning:
<math> 2^3 = 2 \cdot 2 \cdot 2 </math>
and
<math> 2^5 = 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 </math>
Preliminaries
- Know how to visually represent addition, subtraction, multiplication, and powers
- Know what squares (powers of two) and square roots are
- Know what logarithms are
- Know what an equation and the solution of an equation is (note that an equation can have more than one solution!)
- Now tie it all together
- And quick a introduction to radians
Essential
