120 x 100 = 12000
120 times 100 is 12000. Multiplying by 100 shifts every digit two places to the left, so 120 becomes 12000. The same total appears as 1000 x 12, the way a monthly figure becomes a yearly one.
120 × 100 = 12,000
Adding 120 to itself 100 times gives the same answer.
How to get 12000 in your head
Multiplying a whole number by 100 adds two zeros. 120 picks up two zeros and becomes 12000. If you would rather break it up, 12 x 100 = 1200, then multiply by 10 to reach 12000. Both routes are quicker than writing the sum out.
The mistake people make with 120 x 100
“120 times 100” and “120 percent of 100” read almost the same and give answers that are 100 apart in scale. 120 x 100 = 12000. 120 percent of 100 = 120. The word percent divides by 100 before it multiplies, which cancels the 100 you just multiplied by.
Where 12000 turns up
12000 is the yearly total behind 1000 a month, which is why 1000 x 12 lands on the same answer from a different pair. It is also 200 hours once you convert 12000 minutes, and 12000 seconds is 3 hours and 20 minutes.
