In this lesson on addition and multiplication practice, the teacher goes over two problems from the math 60 workbook. The first problem involves adding integers with parentheses, and the teacher clarifies that the parentheses are not necessary. The second problem involves multiplying integers, but because there is a zero present, the answer is simply zero. The teacher also demonstrates how to mentally calculate the multiplication of non-zero integers.
