I need help to convert the number 12,663 to base 13

And convert the number 15,257 to base 13

To simplify the expression (-9)(-7) + 6, you need to follow the order of operations (PEMDAS/BODMAS) which states that you should perform operations inside parentheses first, then evaluate exponents, conduct multiplication and division (from left to right), and finally perform addition and subtraction (from left to right).

Let's break down the steps to simplify this expression:

Step 1: First, multiply -9 and -7.
Multiply -9 and -7 to get a positive number since multiplying two negative numbers results in a positive number: (-9)(-7) = 63.

Step 2: Now, add the result from step 1 to 6.
The expression becomes 63 + 6.

Step 3: Finally, add the numbers together.
63 + 6 = 69.

Therefore, the simplified form of (-9)(-7) + 6 is 69.
