Learn to evaluate expressions using order of operations and simplify formulas with given values of variables.
- How do you evaluate and simplify numerical expressions using order of operations?
- How do you simplify [384 - 3(7 - 2)^3]/3?
- How do you evaluate variable expressions using given values of variables?
- What does s - t(s^2 - t) equal if s = 2 and t = 3.4?
- How do you evaluate (8xy + z^3)/(y^2 + 5) if x = 5, y = -2, and z = -1?
This is a good lesson taught in front of a live class. All examples done in this lesson are explained well. These concepts of simplifying expressions and evaluating with given values are review problems from Algebra.
