Answer 2

Let's break down the given expression step by step:

1. (754,321,221,309) - (456,007 - 307,169)

First, we'll calculate the subtraction inside the parentheses: 456,007 - 307,169 = 148,838

Now, we subtract this result from the first number: 754,321,221,309 - 148,838 = 754,321,072,471

2. 1,000,000 - (296,158 + 575,964)

Now, we'll calculate the addition inside the parentheses: 296,158 + 575,964 = 872,122

Now, subtract this result from 1,000,000: 1,000,000 - 872,122 = 127,878

3. 90,3180,287.5 - 136.4 + 392.91080.4 + 8,400.7 - 4,900

Let's calculate this expression step by step:

90,3180,287.5 - 136.4 = 90,3180,151.1 90,3180,151.1 + 392.91080.4 = 90,3180,543.5 90,3180,543.5 + 8,400.7 = 90,3198,944.2 90,3198,944.2 - 4,900 = 90,3193,044.2

Now, let's put it all together:

754,321,072,471 - 127,878 - 90,3193,044.2 = 754,321,072,471 - 90,3320,922.2

Now, subtract the two numbers:

754,321,072,471 - 90,3320,922.2 ≈ 754,230,751,548.78

So, the result of the expression is approximately 754,230,751,548.78.
