Arithmetic Grade Six

Lesson Five: Carrying

Now for something a little more challenging. Take a look at this example: 

   48
  +75
  ----
STEP ONE: Add the numbers in the ones column. If the the answer is greater than 9, then we must carry: 

   1
   48
  +75
  ----
    3
STEP TWO: Add the numbers in the tens column (including the one which we carried). If the answer is 9 or less just write the answer in the tens column. If the answer is greater than 9 use the hundreds and the tens column. 

   1
   48
  +75
  ----
  123

Here's another example: 


   95
  +87
  ----
STEP ONE: Since the 5 and 7 in the ones column adds up to 12 and 12 is greater than 9, we must carry. 

   1
   95
  +87
  ----
    2
STEP TWO: Adding up the numbers in the tens column we get 18. We use the we place the eighteen in the hundreds and tens column like this: 

   1
   95
  +87
  ----
  182
