Let's roll up our sleeves and solve this. We have 298 and we're going to multiply it by 7, essentially adding 298 to itself 7 times.
Step 1: 0 + 298 = 298
Step 2: 298 + 298 = 596
Step 3: 596 + 298 = 894
Step 4: 894 + 298 = 1192
Step 5: 1192 + 298 = 1490
Step 6: 1490 + 298 = 1788
Step 7: 1788 + 298 = 2086

So, 298*7 = 2086
