Answer 2

To solve this expression, you should follow the order of operations, which is typically remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).

Let's break down your expression step by step:

1. First, solve the expressions inside the parentheses:

   • 150 + 20 = 170
   • 452 + 148 = 600
   • 2 + 12 = 14

2. Next, perform any multiplications and divisions from left to right:

   • 150 + (170 ÷ 5) * (600 ÷ 250) * 14

3. Continue with the multiplications and divisions:

   • 150 + (34) * (2.4) * 14

4. Now, perform the remaining multiplications:

   • 150 + (34 * 2.4 * 14)

5. Finally, calculate the addition:

   • 150 + (119.04)

Now, add 150 and 119.04 together: 150 + 119.04 = 269.04

So, the final result of the expression is approximately 269.04.
