BEDMAS

BEDMAS Is the sequence of operations that must be followed when solving a math sum with several different operations in it.



Brackets=( )

Exponents= a* or ^

Divisions = /

Multiplication=x

Addition=+

Subtraction=-



For eg:


Following the steps of BEDMAS
2x(4+8)/2-1=

1. Bracket..add (4+8)

2x(12/2)-1=
2. divide (12/2)

(2x6)-1
3. multiply(2x6)

12-1=11
4. subtract(12-1)




Here is some to practise:



3x(5+4)/3+3-4=

3x(9/3)+3-4=

(3x3)+3-4=

(9+3)-4=

12-4=8



4+(8/2)-4x2=

4+4-(4x2)=

(4+4)-8=

8-8=0



TIP: Insert a new bracket every time you are doing the next operation in the rule of BEDMAS.
