Solve Decimal Addition: 0.6 + 0.7 Using Visual Blocks

To solve the problem $0.6 + 0.7$, we'll perform simple addition of decimal numbers:

• Step 1: Align the numbers by their decimal points:
       0.6
  +  0.7
• Step 2: Add the numbers column by column, starting from the rightmost digit:

0.6 can be thought of as 0.60 if we want to align them neatly:
       0.60
+     0.70
---------------

• Add the hundredths (rightmost) digit: 0 + 0 = 0
• Add the tenths digit: 6 + 7 = 13. Since this sum is greater than 9, we write down 3 and carry over 1 to the ones column.
• Add the digits in the ones column: 0 + 0 = 0, then add the carried over 1 to get 1.

The result of the addition $0.6 + 0.7$ is $1.3$. This matches our expectations from the arithmetic process.

Therefore, the solution to the problem is $1.3$.
