Rules for expressions v fractions: Fractions - use the slash “/” in between the numerator and also denominator, i.e., because that five-hundredths, go into 5/100. If you space using mixed numbers, be sure to leaving a single space between the totality and portion part.The slash separates the molecule (number above a portion line) and denominator (number below).Mixed numerals (mixed fountain or blended numbers) write as non-zero essence separated by one space and fraction i.e., 12/3 (having the same sign). An instance of a an adverse mixed fraction: -5 1/2.Because slash is both signs for fraction line and division, we recommended use colon (:) as the operator of department fractions i.e., 1/2 : 3.Decimals (decimal numbers) go into with a decimal allude . and also they are immediately converted to fountain - i.e. 1.45.The colon : and slash / is the symbol of division. Have the right to be provided to divide mixed numbers 12/3 : 43/8 or deserve to be used 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 ()<> is mathematics 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• splitting Fractions: 1/2 : 3/4• indexes of fraction: 3/5^3• fountain exponents: 16 ^ 1/2• adding fractions and 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 %• comparing fractions: 1/4 2/3• multiplying a fraction by a whole number: 6 * 3/4• square root of a fraction: sqrt(1/16)• to reduce or simple the fraction (simplification) - separating the numerator and denominator of a fraction by the same non-zero number - indistinguishable fraction: 4/22• expression v brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 of 5/7• fractions multiple: 2/3 that 3/5• division to uncover the quotient: 3/5 ÷ 2/3The calculator follows renowned rules because that order that operations. The most common mnemonics because that remembering this order 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.

GEMDAS - Grouping icons - brackets (), Exponents, Multiplication, Division, Addition, Subtraction. it is in careful, always do multiplication and division prior to addition and also subtraction. Part operators (+ and -) and (* and /) has the exact same priority and also then have to evaluate indigenous left come right.
