Answer 2

To solve the given expressions, let's break them down step by step:

1. 65 * 304 - 55 + 57380 : 95 * 294

We start by performing multiplication and division before addition and subtraction. Using the order of operations (also known as PEMDAS/BODMAS):

65 * 304 = 19,760 95 * 294 = 27,930

57380 : 27,930 = 2.0535 (division operation)

Now let's substitute the values back into the expression:

19,760 - 55 + 2.0535 = 19,707.0535

Therefore, the result is approximately 19,707.0535.

2. 628000 + 628000 + 628000 - 654462 : 309

We again follow the order of operations:

654462 : 309 = 2,118.2314 (division operation)

Now substitute the values back:

628000 + 628000 + 628000 - 2,118.2314 = 1,882,881.7686

Therefore, the result is approximately 1,882,881.7686.

3. 3111 - 7236 : 18 + 2610 : 58 * 45

Following the order of operations:

7236 : 18 = 402 (division operation) 2610 : 58 = 45 (division operation) 45 * 45 = 2,025 (multiplication operation)

Now substitute the values back:

3111 - 402 + 2,025 = 4,734

Therefore, the result is 4,734.

In summary, the solutions to the given expressions are approximately:

1. 65 * 304 - 55 + 57380 : 95 * 294 ≈ 19,707.0535
2. 628000 + 628000 + 628000 - 654462 : 309 ≈ 1,882,881.7686
3. 3111 - 7236 : 18 + 2610 : 58 * 45 = 4,734
