Question

3.7 + 4.31

Explanation:

Step1: Align decimal points

Write the numbers as \( 3.70 + 4.31 \) (adding a zero to 3.7 to have the same number of decimal places for easier addition).

Step2: Add the numbers

Add the hundredths place: \( 0 + 1 = 1 \).
Add the tenths place: \( 7 + 3 = 10 \), carry over 1 to the ones place, write 0 in the tenths place.
Add the ones place: \( 3 + 4 + 1 = 8 \).
So, \( 3.70 + 4.31 = 8.01 \).

Answer:

\( 8.01 \)
