Lesson 2-1
Be able to tell the difference between an expression and an equation.
Be able to evaluate expressions properly using order of operations.
Example 1: How can you tell the difference between an expression and an equation?
Example 2: How can you tell the difference between a numeric and an algebraic
expression?
Example 3: If x=10, what is x2 – 5 x 2
Lesson 2-2 – Translating between Words and Math
Study the chart on pg. 53 outlining the common words used for addition, subtraction,
multiplication, and division.
Example 4: Translate into an expression: Five greater than 4
Example 5: Translate into an expression: The quotient of 6 and 3
Example 6: 62 minus x
Example 7: The product of 52 and y
Example 8: What are the letters called that we use to represent numbers that can
change?
Lesson 2-3 –Solutions to Equations
Be able to determine whether a given number is the solution to an equation.
Example 9: What does solution mean?
Example 10: Substitute x=9 to determine whether it is a solution to the equation x +
2= 11.
Example 11: Substitute s=12 to determine whether it is a solution to the equation s x
2 – 5= 13
Lesson 2-4, 2-5, 2-6, 2-7 – Powers & Exponents
Be able to solve addition, subtraction, multiplication, and division equations
Be able to check your answers.
Example 12: Solve the equation d + 16= 135. Check your answer.
Example 13: Solve the equation w – 12= 45.
Example 14: Solve the equation 5w=135.
Example 15: Solve the equation v/8=40.
Lesson- Inequalities
Be able to solve and graph an inequality on a number line
Remember, if the inequality is less than or equal to OR greater than or equal to, shade
the dot on the number line. Otherwise, leave an open circle.
Example 16: Identify these signs:
a)>
b)<
c)<
d)>
Example 17: Solve and graph this inequality: y +7<9
