In order to multiply easier, set up your work like this:
56
x82
----------
This helps you keep your digits aligned and avoid confusion. What you do is multiply the first number (56) by the "ones" value of the second number (2).
56
x82
------
112
Next, multiply the first number (56) by the "tens" value of the second number (80). You can write this product directly underneath the first product.
56
x82
------
112
4480
Now all you have to do is add both the products.
56
x82
--------
112
4480
--------
4592
Final Answer: 56 times 82 = 4592
