Identify Numbers: Identify the numbers to be added.We have two decimal numbers, 0.626 and 3.46, which we need to add together.
Align Decimal Numbers: Align the decimal numbers for addition.To add the numbers, we should write them one under the other, aligning the decimal points:\begin{align*}
&0.626 \
+ &3.46
\end{align*}This will help us add the numbers correctly.
Add Numbers: Add the numbers.Starting from the rightmost digit, we add each column of numbers. If a column doesn't have a number in one of the rows, we treat it as zero.0.626+3.46−−−−−−−4.086We add 6 to 0 to get 6, 2 to 6 to get 8, and 6 to +3.461 to get +3.462 (we carry the +3.463 to the next column). Finally, we add +3.463 to +3.465 to get +3.461.
