Let's read this big number together: seven hundred forty-two. How do we say it the right way?

Every three-digit number has three places: hundreds, tens, and ones.

Let's start on the left. The seven sits in the hundreds place.

So we say seven hundred.

Next, look at the four. It's in the tens place.

Four tens means forty.

Last, the two is in the ones place.

That's just two.

Now we put the parts together: seven hundred… forty… two.

In word form, we write seven hundred forty-two. Notice the hyphen between forty and two.
