Nathan estimate 67*36 by finding 70*40. will nathan's estimate be greater than or less than the actual product? explain

It would be greater as 67 rounded up is 70 and 36 rounded up is 40 thus, you are multiplying two larger numbers than in your original equation which will result in a larger product.

Nathan's estimate will be lower than the actual product

Step-by-step explanation:

Since 67 is less than 70 and 36 is less than 40, we atomaticly know that the answer will be smaller.

Another way is doing the actual math:

67 times 36 is 2,412

70 times 40 is 2,800
