Method used:

Adding two integers with the unlike sign:

Step 1: Subtract the lesser absolute value from the greater absolute value.

Step 2: Use the sign of the number with the greater absolute value as the sign of the sum.

Calculation:

The given expression is 12 + (-7).

Step 1: Find the absolute values.

|12| = 12 and |-7| =7.

Subtract 12 — 7 to get 5.

Step 2: Here 12 has the greater absolute value and is positive, so the sum is also positive.

That is, 12 + (-7) =5.

Therefore, the sum of the expression 12 + (—7) is 5.

In the case of simple equations without modulo, the solution of $Ax=b$ is $x={A}^{-1}b$, but how to handle this modulo?
