Answer :

Sure! Let's solve the addition step-by-step.

When you add two negative numbers, you add their absolute values together, and then attach a negative sign to the result.

1. Start with the two numbers: [tex]\( -1331 \)[/tex] and [tex]\( -11 \)[/tex].
2. Ignore the negative signs for a moment, and add their absolute values:

[tex]\[ 1331 + 11 = 1342 \][/tex]

3. Since both original numbers were negative, the result of the addition will also be negative.

4. Therefore, the sum of [tex]\( -1331 \)[/tex] and [tex]\( -11 \)[/tex] is:

[tex]\[ -1342 \][/tex]

So, [tex]\((-1331) + (-11) = -1342\)[/tex].
