Hola Mate

Here your answer

(-30 x 15)+(-30(-3))

(-450) (Multiplied with negative digit)+(-30 x -3)

-450+ 90(here two negative numbers are multiplied that's why positive sign is written)

= -360(when there are two numbers with opposite sign one having positive and one having negative in that case we subtract the numbers and if the negative number is bigger than positive number we put the negative sign)

Hope it helps u
