The number of spectators during three successive football matches where 16502, 27244, and 16475. Find the total number of spectators.

We’re given a list of the number of fans at three different matches, and we need to find the total. To do that, we’ll have to add these three numbers together: 16502, 27244, and 16475. Notice how we lined up the units place, tens place, hundreds place, thousands place, and ten thousands place.

Once everything is lined up, we can begin to add. We start all the way on the right with the units place, where we add two plus four plus five. Two plus four is six plus five equals 11. We put a one in our units place and a one in our tens place. We do that because we’re breaking this 11 into two different pieces: 11 is equal to 10 plus one. The one goes in the units place and then one ten goes in the tens place.

In our next step, we move to the left to the tens place where we add one plus four plus seven. One plus four plus seven equals 12. We have 12 tens. We can break that up into two different pieces. We’ll put a two in the tens place for two tens and then a one in the hundreds place for the ten tens. Ten tens is equal to 100.

From there we add our hundreds values up: one plus five plus two plus four. This also equals 12. We write a two in our hundreds place and carry a one into our thousands. Moving one place to the left in the thousands place, we need to add one plus six plus seven plus six.

When you add all of these up, you get 20. For our 20, we’ll put a zero in the thousands place and then we’ll carry a two over to our ten thousands place. In our last step, we’ll add two plus one plus two plus one, which equal six. Carefully adding each of these values together gives us the total number of spectators: 60221.
