The video tutorial explains the zero property in multiplication, particularly focusing on matrices. It introduces the concept of a zero matrix, which, when multiplied by any matrix, results in a zero matrix. The tutorial provides examples to illustrate how the dimensions of the resulting zero matrix can differ from the original matrices. It concludes with a mention of additional resources and encourages viewer engagement.
