Unit 4, Lesson 10
Writing and Expanding Multiplication Expressions
EngageNY 45 min(s)
Students identify parts of an expression using mathematical terms for multiplication. When we want to show multiplication of two numbers like 5 and 7, we typically write 5 × 7, using the "×" to show the operation. When we start to use variables with multiplication, we can use other forms. Why might we want to use a form other than the × when variables are involved?
