In this activity, we will look at how to subtract large numbers.
62,474 - 58,321 = 4,153
Set the numbers out in columns and subtract vertically.
Always begin with the ones column in each calculation.
In this example, 10,000 has to be 'exchanged' or 'regrouped' from 60,000 as we cannot take 8,000 away from 2,000. This is also known as 'borrowing'.
When we carry across 10,000 to 2,000 we then create 12,000.
12,000 - 8,000 = 4,000
We will now solve a series of calculations that require column subtraction.
