27x823 do the math and explain give brainleast
Step2247 [10]

Answer:

22221

Step-by-step explanation:

I set up the problem like this

823

x27

Then I multiplied 7 by 3 and carried over the one and then multiplied 7 by 2 and added one and carried the one over... I then multiplied 7 by 8 and added the one!

Then I put a zero where the 7 I first multiplied would be... I then multiplied 2 by 3 and then multiplied 2 by 2 and finally multiplied 2 by 8!

I then added up the two values! (Sorry this probably sounds confusing!)
