Ok kiddo, we're going to talk about something called strength reduction. Basically, when a computer program is being made, the programmer wants it to be as fast as possible. One way to do this is by making the program use less powerful operations, like adding instead of multiplying.
It's kind of like when you're helping your mom with the groceries. You could carry all the bags at once, but that would be really hard for you and take a long time. So instead, you carry a few bags at a time, which is easier and faster.
Now, back to the computer program. When the programmer uses these less powerful operations, it's called strength reduction. It helps the program run faster by using simpler and more efficient instructions.
Think of it like a race. If you have to run a mile, you could sprint the whole way but you would get tired really quickly. But if you run at a steady pace, you can finish the whole race without getting too tired. So, in the same way, when the programmer uses strength reduction, they're making the program run at a steady pace instead of sprinting the whole time.
In summary, strength reduction is when a programmer uses simpler and more efficient operations in a computer program to make it run faster, like carrying fewer bags at a time or running at a steady pace instead of sprinting.
