Calculator expression with brackets

1/3 * (1/2 - 3 3/8) = -2324 ≅ -0.9583333

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

Calculation steps

  1. Conversion a mixed number to a improper fraction: 3 3/8 = 3 38 = 3 · 8 + 38 = 24 + 38 = 278

    To find new numerator:
    a) Multiply the whole number 3 by the denominator 8. Whole number 3 equally 3 * 88 = 248
    b) Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27
    c) Write previous answer (new numerator 27) over the denominator 8.
  2. Subtract: 12 - 278 = 1 · 42 · 4 - 278 = 48 - 278 = 4 - 278 = -238 = 8 · -238 · 8
    The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 8) = 8. Cancelling by a common factor of 8 gives -238.
    In words - one half minus twenty-seven eighths = minus twenty-three eighth.
  3. Multiple: 13 * the result of step No. 2 = 13 * (-238) = 1 · (-23)3 · 8 = -2324 = -0.958333333333 · 241 · 24
    Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-23, 24) = 24. Cancelling by a common factor of 24 gives -2324.
    In words - one third multiplied by minus twenty-three eighth = minus twenty-three twenty-fourth.

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




Rules for expressions with fractions:

Fractions - use the 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 number 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 non-zero integer separated by one space and fraction i.e., 1 2/3 (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 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.

Colon : and slash / is the symbol of division. Can be used to divide mixed numbers 1 2/3 : 4 3/8 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

Calculator follows well-known rules for order of operations. 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.
