Answer:

10 and 10

Explanation:

So for the first one, 1-(-9), the two subtraction signs cancel each other out and are turned into an addition symbol. The new equation would now be the absolute value of 1 + 9. As we know, 1 + 9 is 10, and the absolute value of 10 is 10. The absolute value just means how many spaces the number is away from 0, and it will always be positive.

For the second one, -9 -1 would equal -10. Even though -10 is negative, the absolute value will always be positive, so the absolute value of the second one is also 10.

Hope this helps and let me know about any questions!
