Hello! So first off, let's do this piece by piece. So, we know that d = 3. We must multiply 6 and 3 together. If you know basic multiplication, you already know that 6 * 3 is 18. Now, let's go to the next part. c = 4. Once again, we do basic multiplication. 2 * 4 is 8. Subtract the two products. 18 - 8 is 10. There. The value is 10.
