• What is adding without regrouping?

Set out the column addition of 417+235 by lining up the hundreds,tens and units digits of each number.

• Adding the digits from right to left,starting with the units column,we have:
• 7+5 = 12.
• 12 contains two digits and so,we write down ‘2’ in the units column and carry the ‘1’ into the tens column.

What is basic addition? Basic addition is the combining of at least two numbers. Basic counting can also be demonstrated with an addition chart as students can learn to recognize patterns as they count.
