Rules for expressions with fractions: Fractions - use a forward slash to lớn divide the numerator by the denominator, i.e., for five-hundredths, enter

**5/100**. If you are using mixed numbers, leave a space between the whole và fraction part.

**Mixed numerals**(mixed fractions or mixed numbers) Keep one space between the integer and

**fraction and use a forward slash to đầu vào fractions i.e., 12/3**. An example of a negative mixed fraction:

**-5 1/2**.

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

**Decimals (decimal numbers) enter with a decimal point .**& they are automatically converted to lớn fractions - i.e.

**1.45**.

**MDAS**- Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule.**Be careful; always do multiplication và division**before**addition and subtraction**. Some operators (+ and -) and (* & /) has the same priority and then must evaluate from left to right.
