Answer 2

Certainly! To add the numbers 2.5 and 18, follow these steps:

Step 1: Align the numbers vertically by their decimal points (if they have any). If one number has a decimal point and the other does not, you can assume the whole number as having an implicit decimal point at the end (e.g., 2.5 can be written as 2.5 and 18 can be written as 18.0).

Step 2: Add the numbers column by column, starting from the rightmost column (the ones place) and moving towards the left.

In the ones place: 5 + 0 = 5

Step 3: Now move to the next column (the tenths place).

In the tenths place: There's no number in the tenths place for 18.0, so we can assume it as 0. So, it's like adding 5 (from the previous step) with 0 in the tenths place.

Step 4: Finally, move to the leftmost column (the whole numbers place).

In the whole numbers place: 2 + 1 = 3

      305

Step 5: Since we don't have any other columns left to add, the result is 305.

Therefore, 2.5 + 18 = 305.
