Explanation:

Problem 1: \( 0.09 - 0.072 \)

Step1: Align decimal points

\( 0.090 - 0.072 \)

Step2: Subtract

\( 0.090 - 0.072 = 0.018 \)

Step1: Align decimal points

\( 82.456 - 50.030 \)

Step2: Subtract

\( 82.456 - 50.030 = 32.426 \)

Step1: Align decimal points

\( 53.500 - 0.094 \)

Step2: Subtract

\( 53.500 - 0.094 = 53.406 \)

Answer:

\( 0.018 \)

Problem 2: \( 82.456 - 50.03 \)
