... • The bottom number in a fraction is called a denominator, it represents the number of equal parts in a whole. • Example -In the picture shown below, there were four peices in one pizza. Four is the denominator because it is the number of parts to the whole. One piece was eaten, leaving three out of ...

Mental Arithmetic Strategies
... The factors of 24 are (1,24), (3,8), (4,6), (2,12) Choose a factor pair which will help you get rid of the .25 when you multiply. For example if we take the factor pair (4,6) we can x 3.25 by 4 and we get 13. (3 x 4 = 12 and 0.25 x 4 = 1, add them to get 13) We then take our answer 13 and mu ...

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.
