6.4. Lesson 10

Open Ended

Why might we want to use a form other than the × when variables are involved?

Multiple Select

Which of these models can be used to show multiplication where there are no variables involved? (select all that apply)

• 5 x 7

• (5)(7)

•  $5\cdot7$  

• 57

DISCUSSION

• When writing expressions using the fewest number of symbols, we have to refrain from using the symbols ×, ∙, or ( ).

• We will also be using math terms to describe expressions and the parts of an expression. We will be using words like factor, product, quotient, coefficient, and term

• A term is a part of an expression that can be added to or subtracted from the rest of the expression. In the expression 7𝑔 + 8ℎ + 3....7𝑔, 8ℎ, and 3 are all terms. 

• A coefficient is a constant factor in a variable term. For example, in the term 4𝑚, 4 is the coefficient, and it is multiplied with 𝑚.
