BIDMAS is also called PEMDAS. I use PEMDAS so I will show you with PEMDAS.
P = Parentheses
E = Exponents
M =Multiplication
D = Division
A = Addition
S = Subtraction
*These go from left to right.
Lets write our question out.
50 + 75 - 82 × 6 =
First we will multiply since that come first from PEMDAS.
50 + 75 - 82 × 6 =
50 + 75 - 492 =
Next we will do
Addition and subtraction right to left.
50 + 75 - 82 × 6 =
50 + 75 - 492 =
125 - 492 =
= -367
So, 50 + 75 - 82 × 6 = -367 when we use BODMAS (In my case PEMDAS).
Hope I helped ya!!!
