Matrix Multiplication (University presentation slide)
Matrix multiplication involves multiplying matrices according to certain rules. A matrix is a rectangular layout of numbers arranged in rows and columns. To multiply matrices, each element in a row of the first matrix is multiplied by the corresponding element in a column of the second matrix and those products are summed to form the element of the product matrix in that row and column. Matrix multiplication is useful in many fields including business, data analysis, geology, and robotics.

Here are the steps to solve problems about equal groups:
1. Read the problem carefully to understand what you are trying to find.
2. Identify the key pieces of information - how many groups there are, how many items are in each group, the total number of items.
3. Set up and solve an equation to find the missing information. If finding how many items are in each group, divide the total items by the number of groups. If finding the number of groups, divide the total items by the number of items in each group.
4. Check that your answer makes sense and addresses what was asked in the original problem.
