Smart Numbers and Problem Solving Techniques

The video tutorial introduces the concept of smart numbers and their application in solving algebra problems. It explains the technique of plugging in numbers, which involves substituting variables with numbers to simplify problem-solving. The tutorial outlines steps for selecting appropriate numbers, solving problems, and using the process of elimination to find correct answers. The approach is particularly useful for multiple-choice questions with variables in the answer choices.

Why is it important to mark key information on your scratch paper?

• To make it look neat

• To avoid using a calculator

• To easily find important details later

• To impress the examiner

What are smart numbers used for in algebra problems?

• To increase the difficulty level

• To avoid using actual algebra

• To confuse the solver

• To make problems more complex

What is the main benefit of the plugging in numbers technique?

• It requires memorizing formulas

• It is a new mathematical operation

• It simplifies solving algebra problems

• It is only useful for geometry

When choosing smart numbers, what should you always consider?

• The rules given in the problem

• The color of your pen

• The length of the problem

• The time of day

Which of the following is NOT a smart number?

• Zero

• One

• Pi

• Two

What should you do when working with percentages?

• Use a negative number

• Use a fraction

• Use a random number

• Use a multiple of 100

What is the first step in solving problems by plugging in numbers?

• Choose a random number

• Pick a number that follows the problem's rules

• Guess the answer

• Use a calculator

How should you mark the solution on your scratch paper?

• With a star or circle

• With a highlighter

• With a red pen

• With a ruler

What does POE stand for in the context of this technique?

• Part of Equation

• Proof of Example

• Point of Entry

• Process of Elimination

What should you do if multiple answer choices remain after elimination?

• Skip the question

• Choose randomly

• Pick a different value for the variables

• Start over
