Rules for expressions through fractions: Fractions - use the cut “/” in between the numerator and also denominator, i.e., because that five-hundredths, enter

**5/100**. If you space using combined numbers, be sure to leave a solitary space between the totality and fraction part.

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

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

**-5 1/2**.

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

**Decimals (decimal numbers) go into with a decimal suggest .**and also they are automatically converted to fountain - i.e.

**1.45**.

**The colon :**and also slash

**/**is the price of division. Deserve to be used to divide blended numbers

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

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

**An asterisk ***or

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

**Plus +**is addition, minus sign

**-**is subtraction and also

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

**The exponentiation/power price is ^**- because that example:

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

**Examples: • including fractions: 2/4 + 3/4• individually fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• splitting Fractions: 1/2 : 3/4• indexes of fraction: 3/5^3• fountain exponents: 16 ^ 1/2• including fractions and mixed numbers: 8/5 + 6 2/7• separating integer and also fraction: 5 ÷ 1/2• complicated fractions: 5/8 : 2 2/3• decimal come 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 entirety number: 6 * 3/4• square root of a fraction: sqrt(1/16)• reducing or simplifying the fraction (simplification) - separating the numerator and denominator that a fraction by the same non-zero number - tantamount fraction: 4/22• expression through brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 the 5/7• fountain multiple: 2/3 that 3/5• divide to find the quotient: 3/5 ÷ 2/3The calculator follows popular rules for order of operations**. The most common mnemonics for remembering this bespeak 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 symbols - base (), Exponents, Multiplication, Division, Addition, Subtraction.

**it is in careful, always do multiplication and also division**prior to

**addition and subtraction**. Some operators (+ and -) and also (* and /) has actually the same priority and also then should evaluate from left come right.
