2. Aim: How do we translate verbal expressions into algebraic expressions?
Do Now: Write a verbal expression for each of the following:
3r + 4
D2 – 17 = 9
2(y + 8) < -5
Be creative! Use the words from your Math-English dictionary. For example, you could say “3 more than twice a number” instead of “2 times a number plus 3”

3. Translating Verbal Expressions into Algebraic Expressions
To translate verbal expressions into algebraic expressions or equations, it’s important to remember these key words.
Addition Keywords –
-Sum, plus, added to, and (if no other operation indicated), more than*, total, increased by
Subtraction Keywords –
-Difference, minus, less than*, subtracted from*, decreased by
Multiplication Keywords –
-Product, multiplied by, times, of
Division Keywords –
-Quotient, divided by, divided into*
*switching phrase

5. A few important notes…
When using the words sum, difference, product, quotient, the two expressions are separated by the word AND
Ex. The quotient of a number squared and twice the same number
“less than” vs. “is less than”
5 less than a number means …
5 is less than a number means …

6. Six less than twice a number.
Let try some examples!!
Six less than twice a number.

7. Five less than half of a number.

8. Four times the difference of a number squared and six.

9. Sixteen less than the quotient of twice a number and five.
