Answer 3

To solve this expression, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, you have parentheses, so you should start by solving what's inside them:

1. Inside the parentheses, you have two divisions to perform: a. 31.45 ÷ 3.7 ≈ 8.5135 (rounded to four decimal places). b. 8.5135 + 4.3 ≈ 12.8135 (rounded to four decimal places).

Now, your expression becomes:

70 - 12.8135 - 3.5

2. Next, perform the subtraction:

   70 - 12.8135 - 3.5 ≈ 53.6865 (rounded to four decimal places).

So, the result of the expression is approximately 53.6865.
