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.
