What are the steps in addition?

The steps in addition involve identifying the numbers to be added, aligning them by place value (units, tens, hundreds, etc.), and then summing each column starting from the rightmost side. If a column's sum exceeds nine, you carry over the extra value to the next column on the left. Finally, you write down the total sum, ensuring all carries are accounted for. This process can be applied to both simple and complex numbers.
