Math 25: Solutions to Homework # 4 (4.3 # 10) Find an integer that
... The total cost was x42y cents. If 88 divides this number, then both 8 and 11 must divide it. We know that 8 | x42y if 8 | 42y. Thus we must have y = 4 since 424 is the only number of this form divisible by 8. Now 11 | x424 only if 11 divides x − 4 + 2 − 4 = x − 6. Thus x = 6, so the total cost was ...

Counting Positive and Negative Input Values
... In the program, Positive and Negative are used to count the number of positive and negative data items, and PosSum and NegSum are used to compute their sums. The program first reads the number of input items into TotalNumber and uses it as the final value in a DO-loop. ...

Arithmetic
Arithmetic or arithmetics (from the Greek ἀριθμός arithmos, ""number"") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.
