... multiplication is commutative—the order we write the numbers in doesn’t matter. For example, 2 × 5 = 5 × 2. ASK: Do you think the same is true for powers—will it matter which number is written as the base and which number is written as the exponent? Have students explain the basis for their predicti ...

... Design an algorithm that will receive two numbers as input, increment the first number by 5, double the value of the second one and then display to the screen their sum and quotient. Note that the quotient calculation (first integer divided by second integer) is only to be performed if the second in ...

... Manipulatives Suppose you have 78 number tiles. Describe how to illustrate 78 ÷13 with the tiles, using each of the three basic conceptual models for division. a. Repeated subtraction. Remove groups of 13 tiles each. Since 6 groups are formed 78 ÷ 13 = 6. b. Partition. Partition the tiles into 13 eq ...

... The problem is to find a rational expression (a fraction) for this decimal, if possible. This is challenging because we have to add up infinitely many non-zero numbers. It’s an interesting philosophical question. (Zeno’s Paradox anyone ? ) In the first place, the only way that infinitely many (nonne ...

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.
