Answer:
837x4=3348
Explanation:
First multiply 7 by 4 which is 28. You keep the 8 as part of your answer, and put 2 above 3 in other words regroup.
Next multiply 3 by 4 which is 12 and add 2 which equals 14. Again, leave the 4 as part of your answer and put the 1 over the 3 in other words regroup.
Then multiply 8 by 3 and add 1 which equals 33.
