Order of operations- The language of Math

Today we learned about the order of operation when calculating a long operation involving several different signs( e.g. addition, subtraction, division ,multiplication etc..). There is a certain way of doing this operations, the method is called BEDMAS. Which stands for

B- Brackets ( ) - it means that you should simplify first all the numbers in a bracket.

E- Exponents 2^{3 - it means that you should simplify numbers in exponent form after you have simplified the numbers inside the brackets.} 2^{3 means 2x2x2.}

^{D- Division}

Note: Multiplication and division are like brothers, whoever comes first to them from LEFT TO RIGHT, you use that first.

M- Multiplication

A- Addition

Note: Addition and subtraction are like sisters, whoever comes first to them from LEFT TO RIGHT, you use that first.

S- Subtraction

Examples:

9094112355 ÷ 3 + 1671541346 - 2 x (50561+215125) x 2.256241=
