- According to the multiplication rule we have 4 formula.
- (+) x (+) = + Multiplying positive sign we get positive.
- (-) x (-) = + Multiplying negative sign we get positive.
- (+) x (-) = - Multiplying positive and negative sign we get negative.
- (-) x (+)= - Multiplying negative and positive sign we get negative.
- Multiplying the value -12 and -35 we get 420 and multiple the value of 25 and -12 we get -300.
- Simplify the given value -300 + 420.
