Book Free DemoWhile, subtraction of 2 integers, depending upon the sign of the two or more integers, the answer can change.
Subtraction on integers:
When two integers have a different sign, the sign of the answer will be the sign of the largest integer and both numbers will be subtracted.
Example:
1. Find the value:
The given expression is (-5) and (9) since these numbers have different signs, so the difference of the numbers are taken, and the answer will have the sign of a larger number.
Hence the answer is +4.
Further examples:
2. (-20) + 13 = -7
3. 30 - 15 = 15
4. 20 + (-10) = 10
5. -30 + 50 = 20
When two integers are subtracted, (+ve)-(-ve), or (-ve)-(-ve), since -ve multiplied by -ve is +ve, the operand between both numbers will be taken as +.
Example:
1. (-10) - (-10) = (-10) + 10 = 0
2. (20) - (-10) = 20 + 10 = 30
3. (-50) - (-15) = -50 + 15 = -35
4. (25) - (-15) = 25 + 15 = 40
When two integers are subtracted, in this manner, (+ve) - (+ve), both integers should be subtracted, and the sign of the answer will be the sign of the highest integer.
Example:
1. 30 - 10 = 20
2. 40 - 12 = 28
3. 10 - 50 = -40
4. 20 - 48 = -28
