This document defines and compares theories and laws. A theory can potentially be proven wrong with new evidence, while a law is very unlikely to be proven wrong and is considered a fact based on extensive evidence and hypotheses. It then provides explanations and examples of exponents, scientific notation, formula transformation, the Pythagorean theorem, trigonometric functions, and unit conversion.

1. DIFFERENCE BETWEEN THEORY AND LAW?
A theory is a statement based on a collection of ideas, observations and hypotheses but CAN STILL BE PROVEN
WRONG.
(THEORY of evolution.)
A law is a stament based on a collection of ideas, observations, and hypotheses that WILL MOST LIKELY NOT BE
PROVEN WRONG and is considered a FACT.

EXPONENTS
The exponent of a number says how many times to use the number in a multiplication.
In 82
the "2" says to use 8 twice in a multiplication,
so 82
= 8 × 8 = 64
Exponents are also called Powers or Indices.
In words: 82
could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"
SCIENTIFIC NOTATION
Scientific notation is a way of writing numbers that are too big or too small to be conveniently written in decimal form.
Scientific notation has a number of useful properties and is commonly used in calculators and by scientists,
mathematicians and engineers.
In scientific notation all numbers are written in the form of
FORMULA TRANSFORMATION
Formula transformation is usually used to transform a shape or a set of points to another shape or set of points. It is a
set of instructions on how to adjust a given shape or point.
PYTHAGOREAN THEOREM
In mathematics, the Pythagorean theorem — or Pythagoras' theorem — is a relation in Euclidean geometry among the
three sides of a right triangle (right-angled triangle). In terms of areas, it states:
In any right-angled triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal
to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).
TRIGONOMETRIC FUNCTIONS
In mathematics, the trigonometric functions (also called the circular functions) are functions of an angle. They relate
the angles of a triangle to the lengths of its sides. Trigonometric functions are important in the study of triangles and
modeling periodic phenomena, among many other applications.
CONVERSION OF UNITS
Conversion of units is the conversion between different units of measurement for the same quantity, typically through
multiplicative conversion factors.
