What is the value of the expression (14+ 2) + 6 x 3-12?

Answer 1

51

Explanation:

To find the value of the expression, you need to simplify it following PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction) If you try and simplify the problem without following the order of operations, you won't always get the right answer.

You want to start by simplifying what is inside the parenthesis.

`(10+5)+6*8-12\\15+6*8-12`

Next you want to do the multiplication:

`15+6*8-12\\15+48-12`

Now we can just combine the rest of the terms

`15+48-12\\51`
