Studdy Solution

STEP 1

Assumptions1. The operations are basic arithmetic addition. . The numbers are integers.
3. The operation follows the standard rules of addition.

STEP 2

For the first problem, we are adding two negative numbers, -2 and -11. The rule for adding two negative numbers is to add their absolute values and then take the negative of the result.
−2+(−11)=−(2+11)-2 + (-11) = - (2 +11)

STEP 3

Calculate the absolute values and add them together.
−2+(−11)=−(2+11)=−13-2 + (-11) = - (2 +11) = -13

STEP 4

For the second problem, we are adding two positive numbers,9 and4. The rule for adding two positive numbers is to simply add their values.
9+4=139 +4 =13

STEP 5

For the third problem, we are adding two negative numbers, - and -1. The rule for adding two negative numbers is to add their absolute values and then take the negative of the result.
−+(−1)=−(+1)- + (-1) = - ( +1)

STEP 6

Calculate the absolute values and add them together.
−6+(−1)=−(6+1)=−-6 + (-1) = - (6 +1) = -So, the solutions to the problems are1. −2+(−11)=−13-2 + (-11) = -13
2. 9+4=139 +4 =13
3. −6+(−1)=−-6 + (-1) = -
