Answer 2

Let's solve each of these math problems:

1. 2 + 39 - 5 + (98 - 65) * 98 / 14 + 15

First, we need to follow the order of operations (PEMDAS/BODMAS):

• Parentheses/Brackets
• Exponents/Orders (none here)
• Multiplication and Division (from left to right)
• Addition and Subtraction (from left to right)

So, let's calculate step by step:

= 2 + 39 - 5 + (33) * 98 / 14 + 15 = 2 + 39 - 5 + 3234 / 14 + 15 = 2 + 39 - 5 + 231 + 15 = 41 - 5 + 231 + 15 = 36 + 231 + 15 = 267 + 15 = 282

So, the answer to the first problem is 282.

2. 6 + 983 * 987 - 764

Let's calculate this:

= 6 + 983 * 987 - 764 = 6 + 970,821 - 764 = 970,827 - 764 = 970,063

So, the answer to the second problem is 970,063.

3. 921 * 758 + 6476 - 7766

Let's calculate this:

= 921 * 758 + 6476 - 7766 = 697,218 + 6476 - 7766 = 703,694 - 7766 = 696,928

So, the answer to the third problem is 696,928.

4. 456 + 757

Let's calculate this simple addition:

= 456 + 757 = 1,213

So, the answer to the fourth problem is 1,213.
