- For multiplication, use the. symbol. A. symbol is optional when multiplying a number by a variable. For instance: 2. x can also be entered as 2x. Similarly, 2. (x + 5) can also be entered as 2(x + 5); 2x. (5) can be entered as 2x(5). The. is also optional when multiplying parentheses, example: (x + 1)(x - 1). Order of Operations.
- Order of Operations Calculator. Type in your sum to see how to solve it step by step. Examples: 2+3.4 or 3/4.3 Description. Just type in sums like these (see Order of Operations for more detail).
- Can be used to divide mixed numbers 1 2/3: 4 3/8 or can be used for write complex fractions i.e. An asterisk. or × is the symbol for multiplication. Plus + is addition, minus sign - is subtraction and is mathematical parentheses.

Rules for expressions with fractions:
Fractions - use the slash “/” between the numerator and denominator, i.e., for five-hundredths, enter 5/100. If you are using mixed numbers, be sure to leave a single space between the whole and fraction part.The slash separates the numerator (number above a fraction line) and denominator (number below).
Mixed numerals (mixed fractions or mixed numbers) write as non-zero integer separated by one space and fraction i.e., 1 2/3 (having the same sign). An example of a negative mixed fraction: -5 1/2.
Because slash is both signs for fraction line and division, we recommended use colon (:) as the operator of division fractions i.e., 1/2 : 3.
Decimals (decimal numbers) enter with a decimal point . and they are automatically converted to fractions - i.e. 1.45.
The colon : and slash / is the symbol of division. Can be used to divide mixed numbers 1 2/3 : 4 3/8 or can be used 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 mathematical parentheses.
The exponentiation/power symbol is ^ - for example: (7/8-4/5)^2 = (7/8-4/5)2
