**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:**$-5+9$

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.**\(20 - 48 = -28\)
