Rules because that expressions through fractions: Fractions - merely use a front slash in between the numerator and also denominator, i.e., for five-hundredths, go into

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

**The slash separates the numerator (number over a fraction line) and denominator (number below).Mixed numerals**(mixed fractions or combined numbers) create as creature separated by one space and portion i.e.,

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

**-5 1/2**.

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

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

**1.45**.

**The colon :**and also slash

**/**is the prize of division. Have the right to be used to divide mixed numbers

**12/3 : 43/8**or can be supplied for write complicated 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 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• dividing Fractions: 1/2 : 3/4• exponentiation of fraction: 3/5^3• spring exponents: 16 ^ 1/2• adding fractions and also mixed numbers: 8/5 + 6 2/7• dividing integer and also fraction: 5 ÷ 1/2• complex fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• fraction to Decimal: 1/4• fraction to Percent: 1/8 %• compare fractions: 1/4 2/3• multiplying a portion by a whole number: 6 * 3/4• square root of a fraction: sqrt(1/16)• reduce or simple the fraction (simplification) - dividing the numerator and denominator that a portion by the same non-zero number - equivalent fraction: 4/22• expression through brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 that 5/7• fractions multiple: 2/3 the 3/5• division to find the quotient: 3/5 ÷ 2/3The calculator follows popular rules because that order that operations**. The most usual mnemonics for 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.

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

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