How do you subtract an integer from another integer without using a number line or counters?

Give an example.

The integer subtraction is goverend by the following the simple rules that the subtarction is normal as the natural numbers but the sign of bigger number comes in the final result. For example: -47 is to be subtracted from + 50 then, result = 50-47 = +3. But, see another example, If -7 is to be subtracted form -8 then , we will write as -8 -(-6) = -8 + 6 = -2. These rules are followed : (-)(-) = + and (-)(+) = - and (+)(+) = +

To subtract an integer from another, change the subtraction into addition by changing the sign of the integer you are subtracting. For example, to calculate 2 - (-4), you convert it to 2 + 4, which equals 6. This method can be applied to any integers to simplify the process.
