PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
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 and division before addition and subtraction. Some operators (+ and -) and (* and /) have the same priority and must be evaluated from left to right.
Examples:
• addition of decimals: -1.5 + 2.45• addition followed subtraction: 5+1-2
• multiplying decimals: 0.25 * 0.2
• division of a decimals: 5.2 / 0.5
• parenthesis: 3 + 7{4 + 3[2-(8 - 4)×3] + 5}×2
• 2nd power and order of evaluation: 6^2-(2*7+4^2)
• cube root: cuberoot(27)
• Convert fraction to a decimal: 3/4
• decimals and mixed numbers: 1.5 - 1 1/5
