The calculator performs basic and advanced operations with fractions, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. Solve problems with two, three, or more fractions and numbers in one expression.

### 1/3 * (1/2 – 3 3/8) = -23/24 ≅ -0.9583333

Spelled result in words is minus twenty-three twenty-fourths.

Conversion a mixed number 3 3/8 to a improper fraction: 3 3/8 = 3 3/8 = 3 · 8 + 3/8 = 24 + 3/8 = 27/8To find a new numerator:a) Multiply the whole number 3 by the denominator 8. Whole number 3 equally 3 * 8/8 = 24/8b) Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27c) Write a previous answer (new numerator 27) over the denominator 8.Three and three eighths is twenty-seven eighths

Rules for expressions with fractions: Fractions – simply use a forward slash between the numerator and denominator, i.e., for five-hundredths, enter **5/100**. If you are using mixed numbers, be sure to leave a single space between the whole and fraction part.**The slash separates the numerator (number above a fraction line) and denominator (number below).Mixed numerals** (mixed fractions or mixed numbers) write as integer separated by one space and fraction i.e., **12/3** (having the same sign). An example of a negative mixed fraction: **-5 1/2**.**Because slash is both signs for fraction line and division, we recommended use colon (:) as the operator of division fractions i.e., 1/2 : 3**.**Decimals (decimal numbers) enter with a decimal point .** and they are automatically converted to fractions – i.e. **1.45**.

**The colon :** and slash **/** is the symbol of division. Can be used to divide mixed numbers **12/3 : 43/8** or can be used for write complex fractions i.e. **1/2 : 1/3**.**An asterisk *** or **×** is the symbol for multiplication.**Plus +** is addition, minus sign **–** is subtraction and **()<>** is mathematical parentheses.**The exponentiation/power symbol is ^** – for example: **(7/8-4/5)^2** = (7/8-4/5)2**The calculator follows well-known rules for 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.** Be careful, always do multiplication and division** before **addition and subtraction**. Some operators (+ and -) and (* and /) has the same priority and then must evaluate from left to right.
