There were 98 birds in a tree. 36 flew away. How many are left?

We start with 98 birds. And 36 of them fly away. If some birds are leaving, that means they’re being taken away from the original amount. And in math terms, that’s called subtraction. So we say minus 36, 98 minus 36.

To solve a subtraction problem like this, we start on the right in the ones place and say eight minus six equals two. After that, we move to the tens place, where we say nine minus three equals six. After 36 birds flew away, 62 birds remained.
