Answer 2

To compare the given expressions without calculating them, we can analyze their structures and identify the key components that determine their relative magnitudes.

1. 45 + 64 * 45 + 46
2. 34 + 60 * 34 + 6
3. 99 - 8 * 99 - 88
4. 77 - 66 * 77 - 16
5. 88 - 55 * 88 - 15
6. 45 + 54 * 45 + 45

Let's break down the expressions:

1. The expression 45 + 64 * 45 + 46 can be simplified as 45 + (64 * 45) + 46. Since multiplication has a higher precedence than addition, 64 * 45 will be larger than the other terms in this expression. As a result, this expression will be the largest among the given ones.

2. The expression 34 + 60 * 34 + 6 can be simplified as 34 + (60 * 34) + 6. Similar to the previous expression, the term 60 * 34 will dominate the result, making this expression the second largest.

3. The expression 99 - 8 * 99 - 88 can be simplified as 99 - (8 * 99) - 88. Here, the multiplication term 8 * 99 will be significant, but the subtraction from 99 will reduce its impact. This expression will be smaller than the previous two.

4. The expression 77 - 66 * 77 - 16 can be simplified as 77 - (66 * 77) - 16. Like the previous ones, the term 66 * 77 will be significant, but the subtraction from 77 will reduce its impact. This expression will be smaller than the previous three.

5. The expression 88 - 55 * 88 - 15 can be simplified as 88 - (55 * 88) - 15. The term 55 * 88 will be substantial, but the subtraction from 88 will decrease its impact. This expression will be smaller than the previous four.

6. The expression 45 + 54 * 45 + 45 can be simplified as 45 + (54 * 45) + 45. Similar to the other expressions, the term 54 * 45 will be significant, but the addition of 45 will reduce its impact. This expression will be smaller than the first two but larger than the remaining ones.

Comparing the expressions in terms of their magnitudes (from largest to smallest):

1. 45 + 64 * 45 + 46
2. 34 + 60 * 34 + 6
3. 99 - 8 * 99 - 88
4. 77 - 66 * 77 - 16
5. 88 - 55 * 88 - 15
6. 45 + 54 * 45 + 45
