16 + (-7) =

Explanation
The given question is a simple addition problem, where we need to add 16 and -7. Adding a positive number and a negative number results in subtracting the absolute value of the smaller number from the absolute value of the larger number, while keeping the sign of the larger number. In this case, the absolute value of 16 is larger than the absolute value of -7. Therefore, we subtract 7 from 16, which gives us 9.

8 + (-19) =

Explanation
The given equation involves adding a positive number, 8, with a negative number, -19. When adding positive and negative numbers, we subtract the smaller absolute value from the larger absolute value and keep the sign of the larger number. In this case, the absolute value of -19 is larger than 8, so we subtract 8 from 19 and keep the negative sign, resulting in -11.

(-6) + (-6) =

Explanation
The given expression (-6) + (-6) represents the addition of two negative numbers. When we add two negative numbers, the result is always a negative number. In this case, adding -6 and -6 gives us -12.

11 + (-24) =

Explanation
The given expression involves adding a positive number, 11, with a negative number, -24. When we add a positive number with a negative number, we can think of it as subtracting the absolute value of the negative number from the positive number. In this case, subtracting the absolute value of -24 (which is 24) from 11 gives us -13. Therefore, the correct answer is -13.

6.

(-11) + (-23) =

Explanation
The given question asks for the sum of -11 and -23. When adding two negative numbers, we add their absolute values and keep the negative sign. In this case, the absolute value of -11 is 11 and the absolute value of -23 is 23. Adding 11 and 23 gives us 34, and since both numbers are negative, the sum will be negative. Therefore, the correct answer is -34.

(-2) + 21 =

Explanation
The given equation (-2) + 21 = 19 is a simple addition problem where we add -2 and 21 together to get the result. When we add -2 and 21, we get a sum of 19. Therefore, the correct answer to the equation is 19.

9.

19 + (-9) =

Explanation
The given expression is a simple addition problem. When we add 19 and -9 together, we get a sum of 10.

10.

(-16) + 20 =

Explanation
When we add a negative number to a positive number, the result will be smaller than the positive number. In this case, we are adding -16 to 20. Since 20 is a positive number, the result will be smaller than 20. The difference between 20 and 16 is 4, so the answer is 4.
