The image is a worksheet titled
"Write the numbers that come before and after", featuring a series of train carriages, each with a number in the middle. The task is to fill in the blank spaces on either side of each number — one for the number that comes
before it and one for the number that comes
after it.
Here's how we solve this:
For each number:
- The number
before is the number that is
one less.
