Question

The textbook uses the analogy of 'navigating a city' to describe problem solving. What does this analogy imply about having a plan?

A plan gives direction and makes it easier to correct course if you get lost

Mathematics is purely about following a map provided by the teacher

A plan is only useful for people who have never visited the city before

A plan ensures you never take a wrong turn

Question

Which of the following numerical statements serves as a counterexample to prove that $\sqrt{a - b} = \sqrt{a} - \sqrt{b}$ is NOT a valid general rule?

Which of the following correctly orders the values from smallest to largest?

X = 5.0 \times 10^{-2}, \quad Y = 0.055, \quad Z = 4.9 \times 10^{-1}

In the 'Look Back' step, why should a student perform a 'quick estimate' of the answer?

Compute the result of the following division, ensuring the final answer is in correct scientific notation: $\frac{2.0\times 10^4}{8.0\times 10^2}$

$\sqrt{100 - 64} \ne \sqrt{100} - \sqrt{64}$

$\sqrt{16 + 9} \ne \sqrt{16} + \sqrt{9}$

$\sqrt{25 - 0} = \sqrt{25} - \sqrt{0}$

$\sqrt{100 \cdot 64} = \sqrt{100} \cdot \sqrt{64}$

To avoid having to use correct units

To determine if the problem was an exercise or a problem

To replace the need for carrying out the plan

To see if the exact answer is significantly different, suggesting an error
