Hello MissP.25_5! 
Let's take the (1,4) entry …
you combine the 1st row of the 1st matrix with the 4th column of the second matrix:
(0 1 1 0 0) and (0 1 0 0 1) …
that's 0*0 + 1*1 + 1*0 + 0*0 + 0*1 = 1

ok, now you try some of the others, and show us what you get (or where you're stuck)

Have you seen the following method for visualizing the multiplication? It should help you to understand how to do matrix multiplication in general. Now please show your work -- you know that you need to show effort before we should offer tutorial help on schoolwork...

That's an interesting diagram. I like it!
FAQ: How does boolean algebra work for multiplying a 5x5 matrix?
1. What is a 5x5 matrix?
A 5x5 matrix is a rectangular array of numbers with 5 rows and 5 columns. It is commonly used in mathematics and computer science for performing operations such as multiplication, addition, and subtraction.
2. How do you multiply two 5x5 matrices?
To multiply two 5x5 matrices, you need to follow the standard matrix multiplication rule. This involves multiplying each element in a row of the first matrix with the corresponding element in a column of the second matrix and then adding all the products. The resulting matrix will also be a 5x5 matrix.
3. What is the order of a product of two 5x5 matrices?
The order of a product of two 5x5 matrices is always 5x5. This means that the resulting matrix will have 5 rows and 5 columns.
4. Can you multiply a 5x5 matrix by a scalar?
Yes, you can multiply a 5x5 matrix by a scalar. This involves multiplying each element in the matrix by the scalar value. The resulting matrix will also be a 5x5 matrix with all elements multiplied by the scalar value.
5. What are some real-world applications of multiplying 5x5 matrices?
Multiplying 5x5 matrices has many real-world applications, such as in computer graphics, quantum mechanics, and economics. It is used to perform transformations in computer graphics, to calculate quantum mechanical operators, and to model economic systems. It is also used in various scientific fields for data analysis and statistical calculations.
