Phase 1

 **B****abylonian Math-**

Though the Babylonian number stuff used only a 60 number system. They did not have to learn 60 different symbols. All of the numbers between 1 and 59 were based on a hard construction of two different cuniform (wedge-shaped) symbols. And, with a little practice, any number could be made using these easy symbols. Symbols is just another word for a meaningful picture. No cats involved in this paragraph.

The Babylonians in the hardness of their mathematics opened the doors for mathematical looking throughout the world, showing that hard mathematics could be performed using systems of algorithms and clever tables. Alot of the mathematics of the Mesopatamian world were forgotten, BUT, with the entrance of the Greeks as the main mathematical group. These new thinkers such as Pythagoras and Euclid were more focused on the geometrical and analytical side of math, other than the practical form of math by the Babylonians and the Egyptians.

Brahmagupta wrote important works on mathematics and astronomy. He has written a 25 chapter book. Brahmasphutasiddhanta, it was the indian book on mathematics or common practice. But because the was no proof. We have no idea where he got it.
 * Brahmagupta-**

Brahmagupta made use of an important concept in mathematics, the number zero. The Brahmasphutasiddhanta(Ill just shorten it to be the B book) is the earliest known text to treat zero as a number in its own right. Rather than as simply a placeholder digit in representing another number as was done by the Babylonians. Or as a symbol for a lack of quantity as was done by Ptolemy and the Romans. In chapter eighteen of his B book, Brahmagupta describes operations on negative numbers.

1. Suppose a farmer has 2800 yards of fencing to enclose a rectangular field. What is the largest area that the farmer can enclose?

2. The owner of a ranch decides to enclose a rectangular region with 460 feet of fencing. To help the fencing cover more land, he plans to use one side of his barn as part of the enclosed region. What is the maximum area the rancher can enclose?

3. A farmer wishes to enclose a rectangular region bordering a river using 4900 feet of fencing. He wants to divide the region into two equal parts using some of the fence material. What is the maximum area that can be enclosed with the fencing?

Phase 3:



How to Graph Quadratic Equations



How to Factor This Particular equation- x^2-18x+80=0 (x-8)(x-10) x=9

How to do the Quadratic Formulae-



x= 18 + or - the square root of -18^2 - 4(1)(80)

2

18+ or - square root of 324 - 360 over 2

18 + or - square root of -36 over 2

18 +or- (-6) over 2

x= 6 or x= 24/2 = 12

Phase 4:

2x^2 - 5x- 4



5 + or - the square root of 5^2 - 4(2)(-4) over 2(2)

which ends up being

5 +or- the square root of 25 + 32 over 4

which is

5 + or - the square root of 57 over 4

meaning it =

5 + or - 7.55 over 4

5 + about 8= 13

x= 13

x also = -3
