### Problem 3: Calculations with Significant Figures

Perform the following calculations, and report your answer to the correct number of significant figures.

**a.**
\[ 2.45 + 18.920 \]

**b.**
\[ 4.009 + 0.0024 - 2.12 \]

In these exercises, remember to pay attention to significant figures in your final answers.

The image contains mathematical expressions labeled as "c." and "d."

c. \(1.0042 \div 0.00621\)

d. \(\frac{(9.187 \times 0.182)}{3.1}\)

Explanation:

- Expression "c" denotes the division of 1.0042 by 0.00621.
- Expression "d" involves the multiplication of 9.187 by 0.182, followed by the division of the result by 3.1. The entire expression is set within a fraction, indicating the order of operations to first perform the multiplication in the numerator before dividing by the denominator.
