Explanation:

To estimate 196 + 4, we can use the given clue which asks us to find a number times 4 that is close to 196. We can start by listing the next 6 multiples of 4: 4, 8, 12, 16, 20, 24. None of these multiples are close to 196. However, we can continue listing multiples of 4 until we find a number that is close to 196. Let's try the next set of multiples: 28, 32, 36, 40, 44, 48. Now we see that 196 is close to 200, which is 48 times 4. So, a reasonable estimate for 196 + 4 is 200.
