What is the first step when adding multi-digit numbers using the standard method?

Write the numbers vertically, aligning the place values.

Explain what 'regrouping' means in the context of addition.

Regrouping is when you have a sum greater than 9 in a place value, and you carry over the tens digit to the next higher place value.

Starting from the ones place allows for proper regrouping when the sum of digits in a column is greater than 9.
