Do not go where the path may lead, go instead
where there is no path and leave a trail.
Ralph Waldo Emerson (1803 – 1882)
Story problems are filled with words
We must translate those words into algebraic
expressions using
Numbers
Variables
Mathematical operation signs
Check out the chart of words on page 78
We must find those Key words and be able
recognize what mathematical operation it describes.
Try it
Four less than a number k
Two more than half of a number f
6 times 4 less than a number p
k 4
f
2
2
6 p 4
Parenthesis are the hard part
Another way to say it: 6 times the quantity of 4 less than a
number t
Write a phrase for the expression
10 decreased by g
The difference between the product of 2 and a
number b and 9 and the number h
10 - g
2b – 9h
Start with the subtraction sign then fill in the
product
