   3507
x    18
--------
  31563     (Step 1: Multiply 3507 by 8)
+ 70140     (Step 2: Multiply 3507 by 10)
--------
 101043     (Step 3: Add the results of steps 1 and 2)

   2340
x    20
--------
  46800     (Step 1: Multiply 2340 by 10)
+  4680     (Step 2: Multiply 2340 by 2)
--------
  51480     (Step 3: Add the results of steps 1 and 2)

Now, let's subtract:
