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

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

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

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

**-5 1/2**.

**Because slash is both signs for fraction line and division, us recommended use colon (:) together the operator of division fractions i.e., 1/2 : 3**.

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

**1.45**.

**The colon :**and also slash

**/**is the symbol of division. Can be used to divide blended numbers

**12/3 : 43/8**or can be provided 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 mathematics parentheses.

**The exponentiation/power price 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• indexes of fraction: 3/5^3• fractional exponents: 16 ^ 1/2• including fractions and also mixed numbers: 8/5 + 6 2/7• separating integer and fraction: 5 ÷ 1/2• complicated fractions: 5/8 : 2 2/3• decimal come fraction: 0.625• portion to Decimal: 1/4• fraction to Percent: 1/8 %• to compare fractions: 1/4 2/3• multiply a portion by a whole number: 6 * 3/4• square root of a fraction: sqrt(1/16)• reducing or simplifying the portion (simplification) - splitting the numerator and denominator the a fraction by the very same non-zero number - tantamount fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 of 5/7• fractions multiple: 2/3 that 3/5• divide to find the quotient: 3/5 ÷ 2/3The calculator follows popular rules because that order the operations**. The most common mnemonics for remembering this stimulate of operations are:

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

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

**BODMAS**- Brackets, that 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**. Part operators (+ and -) and (* and also /) has actually the same priority and then should evaluate from left come right.
