Question

25.9 + (-4.3) =
7.9 - 49.35 =

Explanation:

Step1: Calculate \( 25.9 + (-4.3) \)

Adding a negative number is the same as subtracting its absolute value. So \( 25.9 + (-4.3) = 25.9 - 4.3 \). Performing the subtraction: \( 25.9 - 4.3 = 21.6 \).

Step2: Calculate \( 7.9 - 49.35 \)

When subtracting a larger number from a smaller one, the result will be negative. We can rewrite it as \( -(49.35 - 7.9) \). Calculating \( 49.35 - 7.9 = 41.45 \), so \( 7.9 - 49.35 = -41.45 \).

Answer:

For \( 25.9 + (-4.3) \), the answer is \( 21.6 \).
For \( 7.9 - 49.35 \), the answer is \( -41.45 \).
