Students observe and solve examples of betweenness, ruler postulate, and segment addition postulate. They complete the Finding the Measure of Segments worksheet using the distance formula.

Students develop a matrix to determine the number of differences between each set of primate species. They determine closely related organisms then complete the cladogram and answer a set of questions.

Students review the standards for Algebra I. Using the text, they discover two problems that match each standard and solve them showing all steps on paper. They create a PowerPoint slide for each problem and go through the correct...

Biology aces analyze restriction maps to determine the relationships among different primate species and then complete a cladogram. Preface this lesson with an explanation of how restriction enzymes are used to create the DNA maps....

Sixth graders explore the water displacement method to determine the volume of solid objects such as rocks, nails, and marbles.

Learners demonstrate comprehension of advanced mathematical concepts in Algebra II. The questions check understanding on matrices. Topics include matrix addition, subtraction, and multiplication.

Students learn about matrix addition and subtraction, and scalar multiplication. The tutorial consists of class notes, examples, and practice problems. Review exercises and a chapter quiz are included.

This site has an explanation for many operations of matrices, including equality, addition, subtraction, multiplication, and identity.

Demonstrates how to add and subtract matrices, explains why the addition or subtraction sometimes can't be done, and gives an example of how matrix addition is used in homework problems.

Solve equations where the unknown is a matrix, by using matrix addition and subtraction. Students receive immediate feedback and have the opportunity to try questions repeatedly or receive hints.

Find the matrix that is the result of the addition or subtraction of two given matrices. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Students learn about matrix subtraction, matrix addition, and matrix equations. An assessment is included to check for comprehension of the concepts.

This Computer Algebra System (CAS) activity encourages students to investigate addition, subtraction, and multiplication of matrices. They find the inverse of a matrix. Students also solve a set of linear equations by using matrices.

This over view of matrices begins with an application to electronics using circuit equations. Examples are provided to demonstrate types of matrices, the identity matrix, addition and scalar multiplication of matrices.

Learn how to find the result of matrix addition and subtraction operations.

Find a quick, concise explanation of how to add and subtract matrices. Step by step examples are included to help you understand how to find the sum or difference of matrices of the same dimensions.

Find the matrix that is the result of the addition or subtraction of two given matrices.
