You are watching: 7!/(4!*3!)

## Result:

### 3/4 + 4/7 = 37/28 = 1 9/28 ≅ 1.3214286

Spelled an outcome in indigenous is thirty-seven twenty-eighths (or one and nine twenty-eighths).Rules because that expressions with fractions: Fractions - simply use a front slash in between the numerator and denominator, i.e., because that five-hundredths, go into

**5/100**. If you are using combined numbers, be certain to leave a solitary space in between the totality and portion part.

**The slash separates the molecule (number above a fraction line) and denominator (number below).Mixed numerals**(mixed fountain or blended numbers) create as creature separated by one room and fraction i.e.,

**12/3**(having the exact same sign). An example of a an unfavorable mixed fraction:

**-5 1/2**.

**Because cut is both indications for fraction line and also division, us recommended usage colon (:) as the operator of department fractions i.e., 1/2 : 3**.

**Decimals (decimal numbers) enter with a decimal suggest .**and they are automatically converted to fractions - i.e.

**1.45**.

**The colon :**and slash

**/**is the symbol of division. Have the right to be provided to divide combined numbers

**12/3 : 43/8**or can be provided for write complicated fractions i.e.

**1/2 : 1/3**.

**An asterisk ***or

**×**is the symbol because that multiplication.

**Plus +**is addition, minus authorize

**-**is subtraction and

**()<>**is mathematics parentheses.

**The exponentiation/power price is ^**- for example:

**(7/8-4/5)^2**= (7/8-4/5)2

**Examples: • including fractions: 2/4 + 3/4• subtracting fractions: 2/3 - 1/2• multiply fractions: 7/8 * 3/9• separating Fractions: 1/2 : 3/4• indices of fraction: 3/5^3• spring exponents: 16 ^ 1/2• including fractions and mixed numbers: 8/5 + 6 2/7• splitting integer and fraction: 5 ÷ 1/2• complicated fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• fraction to Decimal: 1/4• portion to Percent: 1/8 %• to compare fractions: 1/4 2/3• multiplying a portion by a totality number: 6 * 3/4• square source of a fraction: sqrt(1/16)• reduce or simple the fraction (simplification) - separating the numerator and denominator of a fraction by the very same non-zero number - tantamount fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• link fraction: 3/4 that 5/7• fractions multiple: 2/3 the 3/5• divide to uncover the quotient: 3/5 ÷ 2/3The calculator follows famous rules for order the operations**. The most typical mnemonics for remembering this bespeak of work are:

**PEMDAS**- Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

**BEDMAS**- Brackets, Exponents, Division, Multiplication, Addition, Subtraction

**BODMAS**- Brackets, the or Order, Division, Multiplication, Addition, Subtraction.

**be careful, always do multiplication and also division**prior to

**addition and also subtraction**. Some operators (+ and also -) and (* and also /) has the same priority and also then must evaluate native left to right.
