Higher Arithmetic
Higher arithmetic, also known as the theory of numbers, is known for its basics of the natural numbers, simple numbers. The numbers, 1, 2, and 3 are numbers that are known as natural numbers. H. Davenport of Cambridge University once said “…in all the records of ancient civilizations there is evidence of some preoccupation with arithmetic over and above the needs of everyday life” (Introduction). The theory of numbers being a science, is simply just a creation invented for the present times. We, as humans, learn regular arithmetic as children, with games such as marbles and other fun counting games. Eventually, as we get to elementary school, we learn the use of addition, subtraction, division, and multiplication, the basics essentially. Math tends become more complex as we move on to middle school and high school. Middle school and high school is where we eventually start using higher arithmetic to understand the current math we are being taught. Although not everyone has an actual rulebook of the higher arithmetic, these laws stand universal. A question can be asked, how important is higher arithmetic? Higher arithmetic is used daily not just by mathematicians, but people of everyday quality. Higher arithmetic is essential, however, it should not be put over human needs and the qualities of everyday life, higher arithmetic simply should be used to make life easier.

Arithmetic has been around for ages. Historians are not entirely sure as to exactly what day and year arithmetic was created, but it is well known it was used during prehistoric times and it came from central Africa. The earliest forms and records of natural numbers were shown in Egyptian and Babylonian history, arithmetic was shown through the forms of tally marks. Arithmetic was also used in Mayan culture, this shown also through tally marks. The theory of numbers is a “pure” branch of math. By “pure” one can analyze that it generally means that, as a science primarily, it...

...Arithmetic is the ABC of math. Addition, subtraction, multiplication, and division are the basics of math and every math operation known to humankind. In one way or another, every equation, graph, and an enormous amount of other things can be broken down into the ABC's of math, the four basic operations. As people say, math is a language, and addition subtraction, multiplication, and division are its alphabet, along with the number line as well. The properties are basically, proven ways to apply the mechanics of arithmetic into certain situations. You can usually find these situations within an equation. Some properties are much more basic and common then others; consequently, they pop up more often then others. For example, the reflexive property of equality, probably the most basic property there is. This property simply states that a number equals itself (a=a). This property is so fundamental that every time you do anything with a number, you see this property come up. When solving a multiple step equation, the only way we can really know that a number, if left alone from one step to the next has stayed the same is because of the reflexive property. This property allows us to establish that 1=1 and anywhere that that specific number comes up, its value is equal to every other number written the same way, "1." This is connected to the mechanics of arithmetic in the sense that all arithmetic operations assume that...

...Divisor | Divisibility condition | Examples |
1 | Automatic. | Any integer is divisible by 1. |
2 | The last digit is even (0, 2, 4, 6, or 8).[1][2] | 1,294: 4 is even. |
3 | Sum the digits. If the result is divisible by 3, then the original number is divisible by 3.[1][3][4] | 405 → 4 + 0 + 5 = 9 and 636 → 6 + 3 + 6 = 15 which both are clearly divisible by 3.
16,499,205,854,376 → 1+6+4+9+9+2+0+5+8+5+4+3+7+6 sums to 69 → 6 + 9 = 15 → 1 + 5 = 6, which is clearly divisible by 3. |
| Subtract the quantity of the digits 2, 5 and 8 in the number from the quantity of the digits 1, 4 and 7 in the number. | Using the example above: 16,499,205,854,376 has four of the digits 1, 4 and 7;four of the digits 2, 5 and 8; ∴ Since 4 − 4 = 0 is a multiple of 3, the number 16,499,205,854,376 is divisible by 3. |
4 | Examine the last two digits.[1][2] | 40832: 32 is divisible by 4. |
| If the tens digit is even, and the ones digit is 0, 4, or 8.
If the tens digit is odd, and the ones digit is 2 or 6. | 40832: 3 is odd, and the last digit is 2. |
| Twice the tens digit, plus the ones digit. | 40832: 2 × 3 + 2 = 8, which is divisible by 4. |
5 | The last digit is 0 or 5.[1][2] | 495: the last digit is 5. |
6 | It is divisible by 2 and by 3.[5] | 1,458: 1 + 4 + 5 + 8 = 18, so it is divisible by 3 and the last digit is even, hence the number is divisible by 6. |
7 | Form the alternating sum of blocks of three from right to left.[4][6] | 1,369,851: 851 − 369 + 1 = 483 = 7...

Now into its eighth edition and with additional material on primality testing, written by J. H. Davenport, The HigherArithmetic introduces concepts and theorems in a way that does not require the reader to have an in-depth knowledge of the theory of numbers but also touches upon matters of deep mathematical signiﬁcance. A companion website (www.cambridge.org/davenport) provides more details of the latest advances and sample code for important algorithms. Reviews of earlier editions: ‘. . . the well-known and charming introduction to number theory . . . can be recommended both for independent study and as a reference text for a general mathematical audience.’ European Maths Society Journal ‘Although this book is not written as a textbook but rather as a work for the general reader, it could certainly be used as a textbook for an undergraduate course in number theory and, in the reviewer’s opinion, is far superior for this purpose to any other book in English.’ Bulletin of the American Mathematical Society

...In the Third Century B.C.E., Euclid formalized, in his book Elements, the fundamentals of arithmetic, as well as showing his lemma, which he used to prove the Fundamental theorem of arithmetic. Euclid's Elements also contained a study of Perfect numbers in the 36th proposition of Book IX. Diophantus of Alexandria wrote Arithmetica, containing 130 equations and treating the essence of problems having only one solution, fraction or integer.
Congruence relation
Modular arithmetic can be handled mathematically by introducing a congruence relation on the integers that is compatible with the operations of the ring of integers: addition, subtraction, and multiplication. For a positive integer n, two integers a and b are said to be congruent modulo n, written:
if their difference a − b is an integer multiple of n (or n divides a − b). The number n is called the modulus of the congruence.
For example,
because 38 − 14 = 24, which is a multiple of 12.
The same rule holds for negative values:
Equivalently, can also be thought of as asserting that the remainders of the division of both and by are the same. For instance:
because both 38 and 14 have the same remainder 2 when divided by 12. It is also the case that is an integer multiple of 12, which agrees with the prior definition of the congruence relation.
A remark on the notation: Because it is common to consider several congruence relations for different moduli at...

...Binary arithmeticArithmetic in binary is much like arithmetic in other numeral systems. Addition, subtraction, multiplication, and division can be performed on binary numerals.
Addition
The circuit diagram for a binary half adder, which adds two bits together, producing sum and carry bits.
The simplest arithmetic operation in binary is addition. Adding two single-digit binary numbers is relatively simple, using a form of carrying:
0 + 0 → 0
0 + 1 → 1
1 + 0 → 1
1 + 1 → 0, carry 1 (since 1 + 1 = 0 + 1 × binary 10)
Adding two "1" digits produces a digit "0", while 1 will have to be added to the next column. This is similar to what happens in decimal when certain single-digit numbers are added together; if the result equals or exceeds the value of the radix (10), the digit to the left is incremented:
5 + 5 → 0, carry 1 (since 5 + 5 = 10 carry 1)
7 + 9 → 6, carry 1 (since 7 + 9 = 16 carry 1)
This is known as carrying. When the result of an addition exceeds the value of a digit, the procedure is to "carry" the excess amount divided by the radix (that is, 10/10) to the left, adding it to the next positional value. This is correct since the next position has a weight that is higher by a factor equal to the radix. Carrying works the same way in binary:
1 1 1 1 1 (carried digits)
0 1 1 0 1
+ 1 0 1 1 1

Arithmetic Sequence is a sequence of numbers in which each succeeding term differs from the preceding term by the same amount. This amount is known as the common difference and can be found using a specific formula by substituting the numbers from the word problem into the equation. When you plug in all the information, you are able to find out the money that needs to be spent and saved in the following word problems.
35. A person hired a firm to build a CB radio tower. The firm charges $100 for labor for the first 10 feet. After that, the cost of the labor for each succeeding 10 feet is $125 more than the preceding 10 feet will cost $125, the next ten feet will cost $150 etc. How much will it cost to build a 90 foot tower?
an=a1+ (n-1) d
a125=100+ (125-1) (150)
a125=100+124(150)
a125=100+18600
a125=18700
sn =n (a1 + an) / 2
= 125 (100+18700) /2
=125(1880) /2
=62.5 (18800) =1175000
The cost to build a 90-foot tower is $11,750.
37. A person deposited $500 in a savings account that pays 5% annual interest that is compound yearly. At the end of 10 years, how much money will be in the savings account?
S+ (0.5) S n=10
S+ (1+0.5) r=1.05
S (1.05) a1= 500(1.05) =525
an= a1(rn-1)
a10=525(1.05-9)
a10=525(1.551328216)
a10=814.4473134
The balance in the savings account at the end of 10 years will be $814.44.
