The result:

2 1/2 - 2/3 = 11/6 = 1 5/6 ≅ 1.8333333

Spelled result in words is eleven sixths (or one and five sixths).
Conversion a mixed number 2 một nửa to a improper fraction: 2 một nửa = 2 1/2 = 2 · 2 + 50% = 4 + 1/2 = 5/2To find a new numerator:a) Multiply the whole number 2 by the denominator 2. Whole number 2 equally 2 * 2/2 = 4/2b) showroom the answer from the previous step 4 khổng lồ the numerator 1. New numerator is 4 + 1 = 5c) Write a previous answer (new numerator 5) over the denominator 2.Two and one half is five halfs.
Rules for expressions with fractions: Fractions - use a forward slash lớn divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole & fraction parts.Mixed numerals (mixed numbers or fractions) keep one space between the integer andfraction & use a forward slash to đầu vào fractions i.e., 12/3 . An example of a negative mixed fraction: -5 1/2.Because slash is both sign for fraction line and division, use a colon (:) as the operator of division fractions i.e., 50% : 1/3.Decimals (decimal numbers) enter with a decimal point .

và they are automatically converted lớn fractions - i.e. 1.45.

The calculator follows well-known rules for the order of operations
. The most common mnemonics for remembering this order of operations are: PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction. GEMDAS - Grouping Symbols - brackets (), Exponents, Multiplication, Division, Addition, Subtraction.

MDAS - Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule. Be careful; always vì chưng multiplication & division before addition và subtraction. Some operators (+ và -) và (* & /) have the same priority & must evaluate from left khổng lồ right.
