Given the imaginary numbers:

-12i x 3i

Determine the product.

Solution:

In multiplying a number, we must take note of the signs. It is a general rule of mathematics when multiplying number with opposite signs, the result will be negative, hence when multiplying numbers with similar signs, the result will be positive. Since we are also given an imaginary number designated with the letter i, we leave the designation as it is.

= -12i x 3i

= -36i

Final answer:
= -36i
