Answer 2

Let's solve each of these math problems step by step:

1. $(349 + 856) + 651$

First, we add the numbers inside the parentheses:

$349 + 856 = 1205$

Then, we add this result to 651:

$1205 + 651 = 1856$

So, the answer is 1856.

2. $166 + 452 + 834 + 748$

We simply add all the numbers together:

$166 + 452 + 834 + 748 = 2200$

So, the answer is 2200.

3. $(837 + 641) - 537$

Again, we add the numbers inside the parentheses:

$837 + 641 = 1478$

Then, we subtract 537:

$1478 - 537 = 941$

So, the answer is 941.

4. $923 - (215 + 623)$

First, we add the numbers inside the parentheses:

$215 + 623 = 838$

Then, we subtract 838 from 923:

$923 - 838 = 85$

So, the answer is 85.
