Rules because that expressions through fractions: Fractions - use the slash “/” between the numerator and denominator, i.e., because that five-hundredths, go into

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

**The slash separates the numerator (number above a portion line) and also denominator (number below).Mixed numerals**(mixed fractions or mixed numbers) compose as non-zero integer separated by one room and portion i.e.,

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

**-5 1/2**.

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

**Decimals (decimal numbers) get in with a decimal point .**and they are immediately converted to fountain - i.e.

**1.45**.

**The colon :**and also slash

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

**12/3 : 43/8**or have the right to be supplied for write facility fractions i.e.

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

**An asterisk ***or

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

**Plus +**is addition, minus sign

**-**is subtraction and

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

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

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

**Examples: • adding fractions: 2/4 + 3/4• individually fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• separating Fractions: 1/2 : 3/4• indices of fraction: 3/5^3• fractional exponents: 16 ^ 1/2• including fractions and mixed numbers: 8/5 + 6 2/7• splitting integer and also fraction: 5 ÷ 1/2• complex fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• portion to Decimal: 1/4• fraction to Percent: 1/8 %• compare fractions: 1/4 2/3• multiply a fraction by a entirety number: 6 * 3/4• square source of a fraction: sqrt(1/16)• reducing or simple the fraction (simplification) - separating the numerator and also denominator of a fraction by the exact same non-zero number - indistinguishable fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• link fraction: 3/4 of 5/7• fountain multiple: 2/3 of 3/5• division to uncover the quotient: 3/5 ÷ 2/3The calculator follows renowned rules because that order the operations**. The most typical mnemonics because that remembering this stimulate of to work 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 icons - base (), Exponents, Multiplication, Division, Addition, Subtraction.

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

**addition and also subtraction**. Part operators (+ and -) and also (* and /) has actually the same priority and also then must evaluate indigenous left come right.
