When you get a complex mathematical equation to solve , you need to keep certain basic rules in mind. Look at the example below.
42 % (9-2) + 6 * 3 - 4
Following the BODMAS
rules you need to solve in the order of Brackets, Off, Division,
Multiplication, addition, and subtraction for the acronym BODMAS.
So in the given equation
Brackets will first be solved. So (9-2) is first solved.
42 % 7 + 6 *3 -4
Next step is to solve the
Division ( 42 % 7)
6 + 6*3 – 4
Next step will be to
solve the multiplication 6*3
6 + 18 – 4
Then addition 6+18
24 – 4
Then the final answer is
24 – 4 = 20
