Turning words into math

*Writing Algebraic Expressions

*Example 1

*u squared plus 3

*Identify the variable

*Look at the words “squared” & “plus”

*Think how can “squared” be notated

*“plus” indicates addition so..

*Then put them altogether

* u2 + 3

u

u2

+ 3

*Example 2

*The product of 7 and y minus y cubed

*Identify the variable

*Look at the words “product”, “minus” & “cubed”

*“product” indicates multiplication, since 7 and y are being multiplied they can be written side by side

*Think how can “cubed” be notated

*“minus” indicates subtraction so..

*Then put them altogether

* 7y – y3

y

7y

y3
