Procedure used:
Adding Two Numbers with Different signs:
"Step 1: Find the larger absolute value minus the smaller absolute value.
Step 2: Use the sign of the number with the larger absolute value as the sign of the sum".
Calculation:
The given expression is (-3) + 4 + (-11).
First, find the value of the expression (-3) + 4.
By using the above procedure, solve the expression (-3) + 4 as follows.
The absolute values of |-3| = 3 and |4| = 4.
Here, the larger absolute value is 4 and the smaller absolute value is 3.
Now, from the larger absolute value subtract the smaller absolute value.
That is, 4-3=1.
In the expression (-3) + 4, the number 4 is the larger absolute value and its sign is positive, so the obtained sum is positive.
That is, (-3) +4 = 1.
Now, substitute (3) + 4 = 1 in the given expression.
(-3)+4+(-11)=1+(-11)
By using the above procedure, solve the expression 1 + (-11) as follows.
The absolute values of |1| = 1 and |-11| = 11.
Here, the larger absolute value is 11 and the smaller absolute value is 1.
Now, from the larger absolute value subtract the smaller absolute value.
That is, 11-1 = 10.
In the expression 1 + (-11), the number 11 is the larger absolute value and its sign is negative, so the obtained sum is negative.
That is, 1 +(-11) = -10.
Therefore, the value of the expression (-3) + 4 + (-11) is -10.

The value of the expression (-3)+4+(-11).
