Addition is the operation of adding one quantity to another.

Corps

In addition, the numbers added together are called addends. The result of an addition is called the sum.

  1. To add numbers with multiple digits, I start by adding the ones. If I have enough ones to form a group of 10, I regroup it to the tens place.

  1. I add the tens and determine if a hundred can be made.

    There are 6 tens. Since I cannot make groups of 10 tens and there are no hundreds, I have finished the addition.

Corps

To add numbers in columns, I have to follow these steps:

  1. I write the numbers one below the other by lining up the digits according to their place value.

  2. I add the ones and I write the ones digit of the sum below the line.
    If there is a ten, I regroup it above the digit in the tens position.

  3. I repeat step 2 for all positions. I do not forget to add the regrouped amount if there is one.
