An expression involves subtracting two numbers from a positive number. Under what circumstances will the value of the expression be negative will be if the negative number is greater than the positive number value. Furthermore, in the basic rule of integers the one that carries the sign of the number has always to be bigger in value.
For example,
1. 2 – 3 = -1
2. 10 + (– 8) + (– 11) = -9
3. -6 + 3 = -3
Hope this helps.
