5^2-2[5(5+4)-25]

Question

Please simplify the above problem

Answer 1

 

5^2-2[5(5+4)-25]

Using pemdas I will solve step by step

5^2 - 2[5(9)-25]

5^2 -2[45-25]

5^2 -2[20]

25- 2[20]

25-40

-15

 

You could obviously combine a couple of steps here and not violate the rules of pemdas or alter the problem but I wanted to show you step by step
