Sure thing, let's get straight to it. We start with 598 and we're going to multiply it by 6, which means adding 598 to itself 6 times.
Step 1: 0 + 598 = 598
Step 2: 598 + 598 = 1196
Step 3: 1196 + 598 = 1794
Step 4: 1794 + 598 = 2392
Step 5: 2392 + 598 = 2990
Step 6: 2990 + 598 = 3588

So, 598*6 = 3588
