Because 400 is an even number, every result in this table is also even. You can see that the last digit repeats in a regular pattern, which makes it easier to spot mistakes when you are doing longer calculations.
Multiples of 400 often end in 0 or 5, which is why they show up so often in money and measurement problems. You can use this pattern to estimate answers in your head before you write them down.
A quick way to generate these multiples on your own is to start from 400 × 10 and move up or down in steps of 400. For example, once you know 400 × 20, you can get 400 × 19 or × 21 by subtracting or adding one more block of 400.
