 what is the value (-8) + (-4) =?



(-8) + (-4) = -12.

When adding two negative numbers, we add their absolute values and then give the result a negative sign. In this case, the absolute value of -8 is 8, and the absolute value of -4 is 4. So, 8 + 4 = 12, and since both numbers are negative, the result is -12.



What happens when we add a negative number and a positive number?


When we add a negative number and a positive number, the result will depend on the absolute values of the numbers and their signs. Here are the three possible cases:

  1. If the positive number has a greater absolute value than the negative number, the result will be positive. For example, 7 + (-4) = 3, because the absolute value of 7 is greater than the absolute value of -4.

  2. If the negative number has a greater absolute value than the positive number, the result will be negative. For example, (-7) + 4 = -3, because the absolute value of -7 is greater than the absolute value of 4.

  3. If the positive and negative numbers have equal absolute values, the result will be zero. For example, 5 + (-5) = 0, because the absolute value of 5 is equal to the absolute value of -5.

In all cases, the sign of the result will be the same as the sign of the number with the greater absolute value.
