The principles of fractions mathematics are the same whether you code them into a calculator or do the math by hand. First, when adding or subtracting fractions you need to start by finding the least common denominator, also known as lowest common denominator or smallest common denominator of the fractions you need to work with. It is by definition the smallest positive integer that is divisible by each denominator. The LCD is the least common multiple (LCM) of the fractions' denominators. This operation is not necessary when doing multiplication, division, or exponentiation. (Source: www.gigacalculator.com)

A number is an arithmetic value which is used to quantify something. A number is also called a numeral. When the numbers are written in a systematic way, it is called a number system. The numbers are classified into different types, namely, real numbers, whole numbers, natural numbers, and so on. In Maths, most of the problems involve integer values. An integer may be either a positive integer or negative integer. The integer follows certain rules and properties during arithmetic operations.

Your calculator will now be working in ‘Math’ mode, and the word Math will be shown near the right-hand side of the top of the calculator display, as shown in Figure 4 below. Math mode is the recommended way of using your calculator during this course as it allows mathematics to be entered and displayed in a similar way to how you would write it on paper.
