Q & A

What is the first problem-solving strategy mentioned in the video?

The first problem-solving strategy mentioned is 'guess and check'.

How does the guess and check method work?

In the guess and check method, you make an initial guess for the answer, check if it meets the problem's conditions, and revise your guess based on the feedback received.

What was the example used to illustrate the guess and check strategy?

The example used involved Pacquiao buying 12 gifts for 840 pesos, where the gifts consisted of books costing 60 pesos each and CDs costing 90 pesos each.

What is the second problem-solving strategy discussed in the video?

The second strategy discussed is to make a table and look for a pattern.

What pattern was identified in the example about trees planted in squares?

The pattern identified showed that each successive square added 8 trees, leading to a total of 36 trees in the fifth square.

How can solving a similar but simpler problem help in problem-solving?

By solving simpler problems, you can identify patterns and strategies that can be applied to more complex problems.

What logical reasoning exercise was provided in the video?

The logical reasoning exercise involved determining which sports four individuals play based on given clues, using a table to organize the information.

What does the strategy of working backwards involve?

Working backwards involves starting from the end result and reversing the steps taken to find the initial condition or amount.

What was the example used to demonstrate the working backwards strategy?

The example involved Lenny's bank account, where she withdrew 1,500 pesos and deposited 4,000 pesos, and the goal was to determine how much was in her account before the withdrawal.

How is an organized list used as a problem-solving strategy?

An organized list helps systematically approach a problem by clearly displaying all possible combinations or outcomes, as illustrated by Michelle's outfits.
