Convenient number
A convenient number is just like your favourite toy or food, something that makes your life easier and more enjoyable.
In the grown-up world, convenient numbers are numbers that are easy to work with when we are doing maths. They are usually rounded numbers that end in 0 or 5, like 10, 15, 20, 25, and 100. We use them to make calculations quicker and simpler.
Think of it like this: when you count your toys or candies, it's much easier to count them in groups of 5 or 10. So, when grown-ups need to count or calculate things, they use convenient numbers to make things easier and faster for them.
For example, if you want to buy 5 pencils that cost $1 each, it's easy to see that you'll need $5 to buy them all. But if you want to buy 7 pencils, it's not as easy to figure out the total cost. But if you use a convenient number like 10, you can see that you need to buy 10 pencils for $10 and then add $1 for the other 2 pencils, making a total of $11.
In short, convenient numbers are numbers that make our lives easier and quicker when we are doing maths.
