Key concepts from this chapter
- Algebra uses letters like x to represent unknown numbers.
- Mathematical operations can be performed on these variables to find patterns.
- The example trick shows that the final answer is always constant regardless of the starting number.
- Changing constants in the steps changes the final result.
- Algebra helps solve mysteries by using logic, not magic.
Important exam questions with answers
Explain why the final answer in the number trick is always 2.
The final answer is always 2 because when we represent the number as x and follow the steps, the expression simplifies to 2. This shows the constant result regardless of the initial number.
How can you change the trick to get a final answer of 3 instead of 2?
To get 3 as the final answer, increase the number added in the steps from 4 to 6. This changes the expression so that after simplification, the result is 3.
Write the algebraic expression for the steps: double the number, add 4, divide by 2, then subtract the original number.
Let the number be x. Doubling it gives 2x, adding 4 gives 2x + 4, dividing by 2 gives x + 2, subtracting x leaves 2 as the final answer.
