2³ - 3(1) =

Question

Need help solving this problem please help me

Answer 1

OK 2 cubed is 2*2*2 = 8 so it becomes 8 - 3(1).

 

3(1) = 3*1 = 3

 

So the problem is 8-3 = ?

 

The answer is 5.  

Answer 2

Nothing comes and more handy than the order of operations and mathematics. Is is PEMDAS. Or an easier way to remember is acronym is: "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

 

This becomes: -3(1) ===> -3

and 2 to the 3 = 2*2*2===>  8

 

So then : 8 - 3 ===> 5
