show how to solve the problem 378 ×6 using place value with regrouping. explain how you knew when to regroup
You should regroup when the product of the two numbers are greatre than nine so 3786 68 is 48 so you would the 8 and regroup the 4 and do the same thing for the rest of the numbers if the product is greater than nine. Your answer will be 2268.
Expand 378 as (300+70+8) then multiply it 6. It will be (300 x 6)+(70 x 6)+(8 x 6)=
1800+420+48=2268
