Khan Academy: Properties of Matrix Multiplication: Zero Matrix

Why does an exponent of zero result in a value of one? Give your classes a concrete explanation for this property that many struggle to remember. A video lesson provides an explanation and provides examples of exponential expressions...

Just as any number remains the same when multiplied by 1, any matrix remains the same when multiplied by the identity matrix. [7:59]

The class explores a real-world application in which the data represents rental prices of beach condos. They problem solve by multiplying matrices to determine the cost of each property in each season. Several scenarios are presented in...

Students learn about the properties of zero, negative, and fractional exponents by watching a video tutorial.

Students explore matrix transformations by examining an example of taking the product of two matrices.

This resource shows how the properties of negative and zero exponents need to be true for the other rules of exponents to hold. In addition, it introduces fractional exponents and shows how to simplify algebraic expressions with negative...

There is one exception to this rule, but all numbers that have a power of zero equal one. Don't believe it? Watch this video as the instructor breaks it down to prove this to be true. This makes solving a problem with a zero exponent...

Visualize matrix multiplication on the coordinate plane. Pupils use the interactive to create a matrix multiplication problem using vectors. The scholars see the resulting product of the matrices as a vector.

Video first explains and gives examples of identity matrices. Then explains what an inverse matrix is and shows how to calculate the inverse of a 2x2 matrix. [14:14]

Some lessons feature videos, some interactive practice problems, and some have notes and activities. This comprehensive look at factoring and solving polynomial equations using the zero product principle has all of this and more. Though...
