Answer 2

To solve the given expressions, follow the order of operations, which is usually abbreviated as PEMDAS:

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the first expression: 864:2+121*3

1. Division: 864 ÷ 2 = 432
2. Multiplication: 121 * 3 = 363
3. Addition: 432 + 363 = 795

Now, let's solve the second expression: 1000-846:2-157359+232*2-288

1. Division: 846 ÷ 2 = 423
2. Subtraction: 1000 - 423 - 157359 + 232 * 2 - 288

Now, we need to do the multiplication before proceeding with the subtraction:

3. Multiplication: 232 * 2 = 464

Continuing with the subtraction:

4. Subtraction: 1000 - 423 - 157359 + 464 - 288

5. Addition and Subtraction (from left to right):

1000 - 423 = 577 577 - 157359 = -156782 -156782 + 464 = -156318 -156318 - 288 = -156606

So, the final result is: -156606
