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.
