Answer 3

Calculations

To compute the given expressions, we can follow these steps:

1. 627 - (400 + 10 + 5) 2. 580 - (102 + 98) 3. 478 - (78 + 394)

Let's calculate each expression step by step.

1. 627 - (400 + 10 + 5) - First, we calculate the sum inside the parentheses: 400 + 10 + 5 = 415 - Then, we subtract the sum from 627: 627 - 415 = 212

2. 580 - (102 + 98) - First, we calculate the sum inside the parentheses: 102 + 98 = 200 - Then, we subtract the sum from 580: 580 - 200 = 380

3. 478 - (78 + 394) - First, we calculate the sum inside the parentheses: 78 + 394 = 472 - Then, we subtract the sum from 478: 478 - 472 = 6

So, the results of the given expressions are: 1. 627 - (400 + 10 + 5) = 212 2. 580 - (102 + 98) = 380 3. 478 - (78 + 394) = 6
