11
Correct Answer
D. 11Explanation
When adding two positive numbers, the result is always positive. In this case, adding +6 and +5 gives us +11. Since the question asks for the result after subtracting 1, we subtract 1 from +11, which gives us the final answer of 11.Rate this question:

Correct Answer
C. 22Explanation
The given expression is subtracting a negative number from a positive number. When subtracting a negative number, it is equivalent to adding the positive value of that number. Therefore, (-3) becomes 3 and the expression simplifies to 19 + 3 = 22.Rate this question:

Correct Answer
A. -5Explanation
When subtracting a negative number from another negative number, we can rewrite the equation as (-29) + 24. Adding a negative number is the same as subtracting a positive number, so (-29) + 24 = -5. Therefore, the correct answer is -5.Rate this question:

Correct Answer
B. 11Explanation
When we add a positive number and a negative number, we subtract the smaller number from the larger number and assign the sign of the larger number to the result. In this case, 13 is a positive number and -2 is a negative number. When we subtract 2 from 13, we get 11. Since 13 is the larger number and it is positive, the result is positive 11.Rate this question:

Correct Answer
D. 19Explanation
The given expression (-6) + (+25) can be simplified by adding the two numbers together. When adding a positive number and a negative number, we subtract the smaller absolute value from the larger absolute value and use the sign of the number with the larger absolute value. In this case, the absolute value of -6 is smaller than the absolute value of +25, so we subtract 6 from 25 and use the sign of 25, which is positive. Therefore, (-6) + (+25) equals 19.Rate this question:

Correct Answer
B. -11Explanation
The given expression (-8) + (-3) is a sum of two negative numbers. When adding two negative numbers, we add their absolute values and keep the negative sign. In this case, the absolute value of -8 is 8 and the absolute value of -3 is 3. Adding these values gives us 11. However, since both numbers are negative, the result is also negative. Therefore, the correct answer is -11.Rate this question:
