Use column subtraction to calculate
the following: 6,458 subtract 3,226.

When we’re subtracting larger
numbers, it helps to use a written method. When we use the column subtraction
method, we subtract in columns, starting with the ones. Then we subtract in the tens
column, the hundreds column, and the thousands column. We could use a place value table to
help. The number we’re subtracting from
is 6,458. This is a four-digit number. The six digit is worth six 1,000s,
the four digit is worth four 100s, the five is worth five 10s, and the eight is
worth eight ones. And we’re subtracting 3,226.

Let’s start by subtracting in the
ones column. We’ve got eight ones, and we need
to subtract six. We know that eight take away six is
two, so we need to write our two in the ones column. Now we can move into the tens
place. What is five 10s take away two
10s? We know that five take away two is
three. So we need to write our three 10s
in the tens place. Moving into the hundreds column,
we’ve got four 100s and we need to take two away. And we know that four take away two
leaves us with two 100s. So we write that in our hundreds
place.

Finally, we can subtract the
thousands: six 1,000s take away three 1,000s. We know that six take away three
leaves us with three 1,000s. So let’s write that in the
thousands place. 6,458 subtract 3,226 is 3,232. We used column subtraction to
calculate the answer.
