OK, let's work through this together. We're starting with 435 and we're going to multiply it by 6, which means we add 435 to itself 6 times.
Step 1: 0 + 435 = 435
Step 2: 435 + 435 = 870
Step 3: 870 + 435 = 1305
Step 4: 1305 + 435 = 1740
Step 5: 1740 + 435 = 2175
Step 6: 2175 + 435 = 2610

So, 435*6 = 2610
