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 23 - it means that you should simplify numbers in exponent form after you have simplified the numbers inside the brackets. 23 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=

Here's a exercise for you to answer.


( 0.75-0.5)x(4.2 ÷0.6)x(4.2÷0.6)+7.3-1.2=


The answer is
