Algebra 2 - Learn how to subtract complex numbers, (3 - 4i) - (2 + 6i)

The video tutorial introduces the concept of imaginary and complex numbers, explaining that 'i' represents the square root of negative one, known as the imaginary unit. It further elaborates on complex numbers, which are expressed as a + bi, where 'a' is the real part and 'bi' is the imaginary part. The tutorial covers operations such as addition and subtraction of complex numbers, emphasizing the importance of combining real parts with real parts and imaginary parts with imaginary parts. The video concludes with examples to illustrate these concepts.
