Adding Numbers with Regrouping
Adding numbers involves combining sets of objects or values to form a new total. It uses the plus sign to join two or more numbers together. When adding multi-digit numbers, you write the numbers in columns, add the ones place value first and then the tens, regrouping values of ten or more to the next column as needed, such as adding 47 + 38 by first adding 7 + 8 in the ones column and regrouping the ten value to the tens column to calculate the full sum.
