Zero matrix

Okay, imagine you have a big box that is filled with numbers. And imagine all the numbers in that box are different, like 1, 2, 3, 4, and so on.

Now imagine if you wanted to create a special kind of box, where all the numbers inside it were just zero. We call this special box the "zero matrix."

So basically, the zero matrix is just a box filled with zeros and nothing else. It can be any size you want, but all the numbers inside have to be zero.

This might not seem very useful at first, but sometimes in math and science, it's really helpful to have a box of all zeros so that we can do some special calculations.

So that's basically what the zero matrix is – just a box that only has zeros inside of it.
